Study on Biodegradable Aromatic/aliphatic Copolyesters
Progress on biodegradable aromatic/aliphatic copolyesters based on aliphatic and aromatic diacids, diols and ester monomers was reviewed. The aromatic/aliphatic copolyesters combined excellent mechanical properties with biodegradability. Physical properties and biodegradability of copolyesters varied with chain length of the aliphatic polyester segment and atacticity of copolyesters. The proces...
متن کاملFormulation selection of aliphatic aromatic biodegradable polyester film exposed to UV/solar radiation
Aliphatic aromatic copolyester films, poly(butylene adipate-co-terephthalate) or PBAT, are susceptible to photodegradation, leading to main chain scission and crosslinking. The presence of crosslinked structures not only decreased the mechanical properties of the film due to embrittlement, but also hindered the biodegradation process by limiting access of water and microorganisms to the polymer...
متن کاملBiodegradation and hydrolysis rate of aliphatic aromatic polyester
The biodegradation and hydrolysis rates of an aliphatic aromatic copolyester were measured in manure, food, and yard compost environments and in phosphate buffer solution (pH 1⁄4 8.0) and vermiculite at 58 C. Mineralization, molecular weight reduction, and structural changes determined by DSC, FTIR, and 1H NMR were used as indicators of the biodegradation and hydrolysis rates. Poly(butylene adi...
متن کاملinvestigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Melt-crystallized crystal morphology and enzymatic degradation mechanism of aliphatic polyester
Crystal morphology of melt-crystallized poly(ethylene succinate) (PES) thin film with a thickness of –100 nm was studied by atomic force microscopy (AFM). The fibril-like and wide or lozenge-shaped PES lamellar crystals under different crystallization conditions are thought to be corresponding to the crystal growth kinetics based on the secondary nucleation theory that there are two regimes of ...
