Polymer microneedles integrated with glucose-responsive mesoporous bioactive glass nanoparticles for transdermal delivery of insulin
Abstract: The traditional subcutaneous or intravenous injection of insulin can not effectively control the release of insulin, resulting in an unregulated the blood glucose levels on diabetic patients. It is urgently to develop a self-controllable insulin delivery system with high sensitivity to the change of blood glucose levels in vivo. In this work, polymer ...

A Soluble Porous Organic Polymer for Highly Efficient Organic-Aqueous Biphasic Catalysis and Convenient Reuse of Catalysts
Functional porous organic polymers (POPs) such as PIM-1 with good solubility have been used for the homogenization of heterogeneous catalysts very recently, in addition to the traditional gas/liquid adsorption and separation. As emerging functional POPs, Azo-POPs have been studied broadly, although they are usually insoluble. This paper reports a novel soluble Azo-POP (named Azo-POP-7) with a fl...

Surface Microstructure Regulation of Porous Polymer Microspheres by Volume Contraction of Phase Separation Process in Traditional Suspension Polymerization System
In the present work, the suspension polymerization method is used for the preparation of porous polymer microspheres with different surface morphology, and the preparation mechanism is systematically expounded. The morphology results show that the smooth, convex, and wrinkled microspheres could be controlled by adjusting the ratio of monomer to porogens.The micelles forming the framework support...

Preparation of surface protein imprinted thermosensitive polymer monolithic column and its specific adsorption for BSA
In this work, a novel thermosensitive surface protein imprinted polymer monolithic column (TsIPMC) was synthesized by combining high internal phase emulsion with 1,1-diphenylethene (DPE) controlled polymerization. Innovatively, DPE and acrylic acid (AA) monomers were introduced in high internal oil and water phases respectively. The research showed that DPE could not only initiate the polymeriza...

【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...

15.【Polymer】Effects of spreading and subphase conditions on the interfacial behavior of an amphiphilic copolymer poly(n-butylacrylate)-b-poly(acrylic acid)
Aggregation behavior of an amphiphilic diblock polyelectrolyte poly(n-butylacrylate)-b-poly(acrylic acid) (PnBA-b-PAA) at the air/water interface and its Langmuir-Blodgett (LB) films were respectively characterized by the Langmuir film balance technique and atomic force microscopy. Effects of spreading solution concentration and volume, and subphase temperature and ionic strength on the interfac...

[Composites Part B-Engineering]Engineering molecular interaction in polymeric hybrids: Effect of thermal linker and polymer chain structure on thermal conduction
In past decades, more research efforts have been devoted to the processing of thermally conductive polymer composite and less on fundamental aspects of heat conduction in polymeric materials. Here we presented a polymeric hybrid system comprising of polymer chain and short thermal linkers that show promising thermal conductivity and optical transparency. This was achieved by engineering their in...
