The use of aerogels in everyday applications is limited due to their high cost and complex preparation process. Drying aerogels can be laborious, requiring significant energy and resources. When prepared as composites, aerogels can enhance mechanical properties. They can also be tailored to release bioactive molecules, such as growth factors or antibiotics, to speed up the healing process. However, there are challenges in using aerogels for wound healing. Large-scale production may be costly, limiting their use in clinical settings. Additionally, the mechanical properties of aerogels may not be suitable for all wound types. Further research is needed to overcome these challenges and optimize the use of aerogels in clinical settings. This research investigates different types of wound dressings, commercial wound dressings, chitosan-based aerogels, and the properties and applications of aerogels in wound dressings. The unique properties of aerogels, such as their high porosity, large surface area, and biocompatibility, make them ideal candidates for enhancing the wound healing process. Studies have shown that aerogels made from chitosan can improve cell adhesion, proliferation, and migration, resulting in quicker and more efficient wound closure. Furthermore, the controlled release of bioactive molecules from aerogels can further improve the healing process by reducing inflammation and promoting tissue regeneration.http://irdpt.ir/Article/47429Aerogel Wound Dressing Antibacterial Chitosan Compositeper ipstsپژوهش و توسعه فناوری پلیمر ایران 2538-3345 2588-39332024-10921930articlePolymeric Electrolytes based on Organosilicon Compounds for Novel Batteries Yones Mosaei Oskoeimosaei@mut.ac.ir1Hamidreza Heidarnezhadhrh@mut.ac.ir2Malek Ashtar University of Technology, Tehran, IRANIn order to achieve the higher energy density in lithium-ion and lithium-metal batteries, the use of electrolytes with desirable properties is a key factor. However, it is necessary to reduce or eliminate the disadvantages of conventional electrolytes such as irreversible decompositions and uncontrolled interfacial reactions, leading to the higher performance and safety of batteries. In this regard, the use of polymeric organosilicon compounds in electrolytes is of great industrial interests due to favorable properties such as non-toxicity, easy chemical modification, non-flammability, low glass transition temperature, high chemical and thermal stability and lower vapor pressure compared to traditional electrolytes. Accordingly, in the last decade, several efforts have been made to improve and develop the performance of polymeric electrolytes based on organosilicon compounds. This paper reviews recent developments in the field of properties and performance of polymeric electrolytes based on organosilicones for use as liquid, gel or solid state electrolytes in lithium-ion and lithium-metal batteries. Different types of polymeric electrolytes based on organosilicon compounds such as polysiloxane and polyhedral oligomeric silsesquioxanes were discussed from the point of view of the role of molecular structure in ionic conductivity, thermal stability, chemical and electrochemical stability, as well as the safety of the respective batteries.http://irdpt.ir/Article/47531Polymeric Electrolytes Organosilicon Compounds Batteries lithium-ion lithium-metalper ipstsپژوهش و توسعه فناوری پلیمر ایران 2538-3345 2588-39332024-10923149articlePolymers and Solvents Used in Membrane Fabrication: A Review Focusing on Sustainable Membrane DevelopmentFarzad Mehrjomehrjo@kashmar.ac.ir1    Membrane technology has been used for a decade in liquid and gas separation due to its relative ease in manufacturing and operation, high selectivity rate and lack of adsorbent regeneration. Membranes can be classified based on the synthesis material and are divided into organic (polymeric) and inorganic membranes. Different methods have been applied to fabricate polymeric membranes with nonsolvent induced phase separation (NIPS) being one of the most widely used. In NIPS, a solvent or solvent blend is required to dissolve a polymer or polymer blend. N-methyl-2-pyrrolidone (NMP), dimethylacetamide (DMAc), dimethylformamide (DMF), and other petroleum-derived solvents are commonly used to dissolve some petroleum-based polymers. However, these components may have negative impacts on the environment and human health. Therefore, using greener and less toxic components is of great interest for increasing membrane fabrication sustainability. The chemical structure of membranes is not affected by the use of different solvents, polymers, or by the differences in fabrication scale. On the other hand, membrane pore structures and surface roughness can change due to differences in diffusion rates associated with different solvents/co-solvents diffusing into the non-solvent and with differences in evaporation time. (2) Therefore, in this review, solvents and polymers involved in the manufacturing process of membranes are proposed to be replaced by greener/less toxic alternatives. The methods and feasibility of scaling up green polymeric membrane manufacturing are also examined.http://irdpt.ir/Article/47996Polymeric membranes Bio-derived solvent Non-solvent induced phase separation Membrane fabrication Scale-upper ipstsپژوهش و توسعه فناوری پلیمر ایران 2538-3345 2588-39332024-10925163articleButyl Rubber Market Analysis in the world: Current situation and future forecastZohre TaherkhaniZTAHERKHANI@GMAIL.COM1masume sajadianm.sajadian@acecr.ac.ir2fatemeh asadifasadi.30@guest.ut.ac.ir3 Chemical Process Design Research Group, ACECR-Tehran Organization, 1417613131, Tehran, Iran Chemical Process Design Research Group, ACECR-Tehran Organization, 1417613131, Tehran, IranChemical Process Design Research Group, ACECR-Tehran Organization, 1417613131, Tehran, IranButyl rubber has many applications in various industries due to its unique properties such as low gas and water permeability, relatively high coefficient of friction and chemical and thermal resistance. By considering the variety of applications and consumption of this material, it is important to investigate the market of butyl rubber in the world. Therefore, in this paper, the amount of supply and demand, analysis of market trends, effective parameters and the forecast of the future market of butyl rubber in different countries are discussed. The data shows that China and Japan are the largest producers of butyl rubber in the world and 28% of the world's total capacity is in these two countries. Also, China is the largest consumer of butyl rubber with consumption of about 35% of the global capacity, and North America is the next with consumption of about 15%.  The market of butyl rubber in the world is equal to 1.629 million tons in 2023 and the export and import volume is 822 thousand tons.

Box 14665517, Tehran, Iran.  Scale deposition is one of the problems that occur in water-containing ions of sparingly soluble salts. One of the common methods for controlling scale deposition is the use of anti-scale agents. To control of scale in cooling water systems, water treatment processes, and oil operations, large amounts of polymeric scale inhibitors are used. Like most traditional polymers, scale inhibitors are designed for long-term durability and remain for years after being discarded. With increasing environmental concerns and discharge limitations, the chemistry of scale inhibitors has shifted towards the use of "green anti-scale agents" that are easily degradable, have minimal environmental mobility, and thus have a lesser environmental impact. This presents a challenge to provide acceptable levels of efficiency with economical dosages. Numerous reports have been published on the chemistry and new products of scale inhibitors that are more environmentally acceptable than conventional anti-scale agents. This review article provides a summary of efforts to develop economical and environmentally harmless scale inhibitors. Currently, the most promising green-scale inhibitors are based on polyaspartic acid. However, there is very limited field operational data, and the widespread use of polyaspartic acid scale inhibitors is awaiting further experience in field operations.http://irdpt.ir/Article/48090Scale green inhibitor polyaspartic acid biodegradability stabilityper ipstsپژوهش و توسعه فناوری پلیمر ایران 2538-3345 2588-39332024-10927788articlePolymer-Based Triboelectric NanogeneratorsSara Tarashis.tarashi@ut.ac.ir1Triboelectric nanogenerator technology has invented new ways to collect ambient mechanical energy with high efficiencies and hence revolutionized clean sustainable energy production.
