Genipin-cross-linked silk sericin/polyN-isopropylacrylamide IPN hydrogels: color reaction between silk sericin and genipin, pore shape and thermo-responsibility
To investigate the color reactions between naturally cross-linking agent genipin and silk sericin (SS), a series of genipin/SS film with adjustable color were firstly fabricated and analyzed by FTIR, UV/Vis and colorimetric methods. Then under the various genipin/SS contents, double cross-linked genipin/SS/Poly(N-isopropyl- acrylamide/N,N0-Methylene-bis-acrylamide) (HMGX) hydrogels were prepared, ...

[J. Mater. Chem. B] Thermo and pH dual-controlled charge reversal amphiphilic graft copolymer micelles for overcoming drug resistance in cancer cells
Currently, multidrug resistance (MDR) is the major challenge of nanotechnology in cancer treatment. In this study, a series of amphiphilic poly(styrene-co-maleic anhydride)-graft-poly(2-(N,N-dimethylamino)ethyl methacrylate) graft copolymer [PSMA89-g-P(DMA16-co-SD)] micelles were prepared. PSMA89-g-P(DMA16-co-SD) graft copolymers were first synthesized by grafting different amounts ...

[Polym. Chem.] A branching point thermo and pH dual-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N-diethyl aminoethyl methacrylate)
We report the design and synthesis of a branching point stimuli-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N- diethylaminoethyl methacrylate) through combined “A2 + BxC” (x > 2) double monomer polymerization and parallel click reaction. The results of ultraviolet-visible spectrophotometry and dynamic light scattering (DLS) indicated that the r...

Thermo- and pH-responsive Behaviors of Aqueous Poly(acrylic acid)/Poly(4-vinylpyridine) Complex Material Characterized by ATR-FTIR and UV-Vis Spectroscopy
A novel thermo- and pH- responsive poly(acrylic acid) (PAA)/poly(4-vinylpyridine) (P4VP) aqueous material with an upper critical solution temperature (UCST) was developed in this study. It was found that the formation of the aqueous complex material was caused by the deprotonation of pyridinium groups of P4VP molecules and consequent hydrogen bonding formation between pyridine and carboxyl...

High Molecular Weight Poly(butylene succinate-co-butylene furandicarboxylate) Copolyesters: From Catalyzed Polycondensation Reaction to Thermo-mechanical Properties.
Novel potentially biobased aliphatic−aromatic copolyesters poly(butylene succinate-co-butylene furandicarboxylate)
(PBSFs) in full composition range were successfully synthesized from 2,5-furandicarboxylic acid (FA), succinic acid (SA),
and 1,4-butanediol (BDO) via an esterification and polycondensation process using tetrabutyl titanate (TBT) or TBT/La(acac)3
as catalyst. The copolyesters...
