Bioinspired Design and Synthesis of Polyphenolic Star-Like and Hyperbranched Polyester Models. [PDF]

Chemistry
Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Multifunctional Electrospun Phase Change Material Mats for Solar-Thermal Energy Storage and Photothermal Conversion. [PDF]

Small Sci
Electrospun polyester‐based phase change mats were functionalized with biochar, graphene, or polypyrrole to enhance photothermal performance. The composites maintain fibrous morphology while achieving tunable mechanical, thermal, and electrical properties. Polypyrrole‐coated mats show significantly improved light‐to‐heat conversion, demonstrating their

Lignin-Sourced Aromatics for Biodegradable Flexible Copolyesters Mimicking Poly(Butylene Adipate-co- Terephthalate). [PDF]

ChemSusChem
In this study, two series of novel PBAT‐mimicking copolyesters are introduced by exploiting lignin‐based building blocks. This class of copolyesters exhibits good barrier properties and biodegradability, paving the way for terephthalate‐free, biodegradable, flexible copolyesters. Poly(butylene adipate‐co‐terephthalate) (PBAT) is an important commercial

Recent progress of heterocycle ring-opening (co)polymerization for the synthesis of sequence-controlled block polyesters and polycarbonates. [PDF]

Smart Mol
Block copolymers are fundamental for the development of smart molecules. Aliphatic polyesters and polycarbonates have received attention as heteroatom‐containing polymers that are biodegradable and biocompatible. Block polymers from polyesters and polycarbonates have the ability to form smart molecules. This review presents the heterocycle monomer ring‐

Molecular Simulations of Polymer-based Drug Nanocarriers: From Physical and Structural Properties to Controlled Release. [PDF]

Adv Healthc Mater
Polymer‐based drug delivery systems can effectively overcome the limitations of free drugs in terms of solubility, stability, and plasma half‐life, yet their development has traditionally relied on time‐consuming trial‐and‐error approaches. This review highlights recent advances in applying molecular simulation to the design of polymer‐based drug ...
