Polylactic acid or polylactide (PLA) can form amorphous, semicrystalline, highly crystalline structure. In this paper, we provide a model for semicrystalline PLA under strain-induced dual-phase transformation, between mesomorphization and crystallization. the proposed constitutive model, use an internal state variable approach by considering initial microstructure, intermolecular features, pref...

Melt electrospinning of polylactide (PLA) loaded with chloramphenicol (CAM) has been performed and characteristics fibers, physical properties scaffolds, CAM release behavior, antibacterial biocompatibility have evaluated. The interest samples is nowadays enhanced for biomedical applications since this antibiotic demonstrated to be efficient the treatment cancer. selected as an ideal preparatio...

INTRODUCTION With the development of living cationic polymerization of isobutylene (IB)1 and styrenic monomers,2–5 the synthesis of ABA triblock copolymer thermoplastic elastomers (TPEs) with polyisobutylene (PIB) as rubbery middle segments and styrenic polymers as plastic outer segments became possible. TPEs with PIB rubbery segments inherently exhibit superior oxidative, chemical and thermal ...

Rare earth luminescent material CaAlSiN3:Eu2+ (CEu) was applied and modified with (3-Aminopropyl) triethoxysilane (KH550) to obtain two types of rare conversion agents, CEu KH550-modified (KCEu). Two kinds polylactide (PLA) films were successfully prepared through solution blending. The results showed that the addition complex increases crystallinity PLA. More importantly, both PLA/CEu PLA/KCEu...
