WebDec 29, 2024 · PBAT is produce d by polycondensation of terephthalic acid, adipic acid and butanediol. With aliphatic and aromatic segments, i t contains a flexible fatty chain, which give it g ood flexibility of molecular chain. Due to the flexibility and high elongation at break, PBAT and its composite are widely used as biodegradable blown film products.

WebSep 18, 2012 · PBAT is an aliphatic-co-aromatic co-polyester synthesized by esterification of 1, 4-butanediol with aromatic dicarboxylic acid and then polycondensation with succinic acid. PBAT has many advantages among all the biodegradable materials, including high flexibility, excellent impact strength and melt processibility. WebMay 19, 2024 · Aromatic ring in PBAT acts as a sink and delocalized radicals created by UV ray so less chain scission is resulted. The degradation might be due to ester chain scission and crosslinking which made the polymer brittle and led to weight loss. 3.4 FTIR spectrum of nanoparticles.
