【Polymer Chemistry】Thermo-and oxidation-responsive homopolypeptide: synthesis, stimuli-responsive property and antimicrobial activity
Abstract:
A homopolypeptide with a thioether spacer and a reactive chloro side-chain end group, namely PBLG-S-Cl, can be readily prepared by n-butylamine initiated ring-opening polymerization of γ-4-(substituent)benzyl-L-glutamate acid based N-carboxyanhydride (NCA) monomer. Cationic polypeptides (PBLG-S-ImX, X = I, BF4) with upper critical solution temperature (UCST)-type thermo- and oxidat...

Biobased flexible aromatic polyester poly(1,5-pentylene terephthalate) (PPeT): Revisiting melt crystallization behaviors and thermo-mechanical properties.
Poly(1,5-pentylene terephthalate) (PPeT) is a less studied member of the family of terephthalic polyesters. The presence of flexible pentylene moiety and foreseeable commercialization of bio-based 1,5-pentanediol (PeDO) could make PPeT an attractive polymer. However, as a semi-crystalline flexible polyester, previous studies indicated that PPeT was hardly to crystallize nonisothermally from melt...

（Macromol. Mater. Eng.）A Thermo- and Moisture-Responsive Zwitterionic Shape Memory Polymer for Novel Self-Healable Wound Dressing Applications
Developing wound dressings that have strong adhesion strength without
causing any conglutination to the wound site is still challenging. Herein,
is proposed that zwitterionic shape memory polymers can be applied as
promising candidates for wound dressing. Sulfobetaine methacrylate (SBMA)
is copolymerized with 2,3-dihydroxypropyl methacrylate (DHMA) in the presence
of boric aci...

(Macromol. Rapid Commun)LCST-Type Hyperbranched Poly(oligo(ethylene glycol) with Thermo- and CO2-Responsive Backbone
A novel hyperbranched lower critical solution temperature (LCST) polymer with sharp temperature and CO2-responsive behaviors is presented in this study. The target polymer of hyperbranched poly(oligo(ethylene glycol) (HBPOEG) is constructed using POEG as the backbone and tertiary amines as branch points. Phase transition of HBPOEG in aqueous solution is investigated by heating and cooling the sy...

Effect of curing conversion on the water sorption, corrosion resistance and thermo-mechanical properties of epoxy resin
The study of the relationship between curing conversion and the properties of the material is critical for optimizing the performance of epoxy materials. In this article, the change in the thermo-mechanical and corrosion resistance properties of the diglycidyl ether of a bisphenol A/diaminodiphenylsulfone epoxy system with curing conversion was studied using various instruments. The water sorpti...

31. Sustainable epoxy resins derived from plant oils with thermo- and chemo-responsive shape memory behavior
Sustainable epoxy resins derived from plant oils with thermo- and chemo-responsive shape memory behavior
Shape-memory epoxy resins were synthesized using plant oils and cellulose nanocrystals (CNCs). Epoxidized soybean homopolymers (PESBMA) were grafted from CNCs using surface-initiated atom transfer radical polymerization (SI-ATRP). The polymer grafted CNCs were combined with P(ESB...

Synthesis and thermoresponsive behaviors of thermo-, pH-, CO2-, and oxidation-responsive linear and cyclic graft copolymers
Rational macromolecular design allows us to construct multiresponsive architectural polymers with a potential toward multipurpose applications. This study aims at synthesis and LCST-type thermoresponsive behaviors of multisensitive linear and cyclic graft copolymers with polyacrylamide backbone and hydrophilic PEG grafts. The cloud point could be tuned by many factors, and the e?ect of cyclizati...

Facile synthesis of thermo-, pH-, CO2- and oxidation-responsive poly(amido thioether)s with tunable LCST and UCST behaviors
The simple and straightforward construction of multi-responsive systems with tunable LCST and UCST dual phase transitions is a great challenge. This study a?ords an e?cient route to tune cloud points via control over the chemical composition of hydroxyl and diethylamino bearing poly(amido thioether)s which were prepared by one-pot thiol–amine–acrylate polyaddition. Owing to the balance of inter/...

Dually pH/reduction-responsive vesicles for ultrahigh-contrast fluorescence imaging and thermo-chemotherapy-synergized tumor ablation
Smart nanocarriers are of particular interest as nanoscale vehicles of imaging and therapeutic agents in the field of theranostics. Herein, we report dually pH/reduction-responsive terpolymeric vesicles with monodispersive size distribution, which are constructed by assembling acetal- and disulfide-functionalized star terpolymer with near-infrared cyanine dye and anticancer drug. The vesicular n...
