【Macromolecules 】Inducing New Crystal Structures through Random Copolymerization of Biodegradable Aliphatic Polyester
The crystal structures of poly(hexamethylene sebacate-co-hexamethylene adipate), P(HSe-co- HA), copolymers have been studied with Fourier transformation infrared spectroscopy (FTIR) and X-ray fiber diffraction. All characteristic FTIR absorption bands of the crystals of HSe and HA comonomers are present in all copolymers, and each copolymer has only one melt temperature, which supports that P(HS...

Tough and Responsive Oppositely Charged Nanocomposite Hydrogels for Assembled Bilayer Actuators Through Interfacial Electrostatic Attractions
Responsive nanocomposite (NC) hydrogels are widely recognized as strong and tough soft
materials for smart devices, but yet with challenges in the synthesis of such
hydrogels and the fabrication of devices. This work reports on a versatile
synthesis of nanocomposite polyelectrolyte hydrogels with high strength and
toughness by using either cationic or anionic monomers, and demon...

Disclosing the formation of ring-banded spherulites for semicrystalline polymers through the double-layer film method
The formation of ring-banded spherulites in double-layer semicrystalline polymer films has seldom been
a concern. In this study, the nucleation and growth of ring-banded spherulites in poly(ethylene oxide)/poly(L-lactide) (PEO/PLA) double-layer films during isothermal crystallization at various temperatures above the melting point of the PEO layer have been investigated by using polariz...

Tunable nanochannels through graphene oxide/polymer core-shell nanosheets for enhanced proton conductivity
Simultaneous manipulation of the topological
structure and chemical structure of the ionic nanochanels within solid electrolyte has
been proved a crucial but challenging task for the rational design of high-performance
electrochemical devices including proton exchange membrane fuel cell. Herein,
we present a novel approach to the construction of tunable nanochannels via direct assembly of graphene...

【Colloids and Surfaces B: Biointerfaces】Facile fabrication of bactericidal and antifouling switchable chitosan wound dressing through a ‘click’-type interfacial reaction
Abstract:
A facile approach to functionalize chitosan (CS) non-woven surface with the bactericidal and antifouling switchable moieties is presented. Azlactone-cationic carboxybetaine ester copolymer was firstly prepared, then chemically attached onto CS non-woven surface through the fast and efficient ‘click’-type interfacial reaction between CS primary amines and azlactone moieti...

The stability of covalently immobilization of TEMPO on the polymer surface through ionic liquid linkage: a comparative and model research.
Covalently immobilizing the active sites or ligands on a polymer surface is an efficient strategy to achieve a full use of expensive organic parts. In this work, 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) was anchored onto polystyrene beads through an ether bond or an ionic liquid bridge. We quantitatively compared their thermal stabilities at nitrogen atmosphere and their chemical stabilities i...
