（ACS Appl. Mater. Interfaces）2D-to-3D Shape Transformation of Room-Temperature- Programmable Shape-Memory Polymers through Selective Suppression of Strain Relaxation
Although shape-memory polymers (SMPs) can alter their shapes upon stimulation of environmental signals, complex shape transformations are usually realized by using advanced processing technologies (four-dimensional printing) and complicated polymer structure design or localized activation. Herein, we demonstrate that stepwise controlled complex shape transformations can be obtained from a single...

Recyclable Crosslinked High-Performance Polymers via Adjusting Intermolecular Cation–π Interactions and the Visual Detection of Tensile Strength and Glass Transition Temperature
Crosslinked high-performance polymers have many industrial applications but are diffcult to recycle. Visual detection of the physical properties of the crosslinked high-performance polymers is useful, but is diffcult to achieve. The crosslinked high-performance polymers (SPIN) are constructed by using cation–π interactions. The cation–π interaction between the polymer side chains can be...

【Carbohydrate Polymers】Hydroxypropylmethyl cellulose (hpmc) crosslinked chitosan (ch) based scaffolds containing bioactive glass (bg) and zinc oxide (zno) for alveolar bone repair
Abstract:
The success of a dental implant relies on the presence of an optimal alveolar ridge. The aim of this study was to fabricate HPMC crosslinked chitosan based scaffolds for alveolar bone repair. Our results indicated that HPMC crosslinked CH/BG foams presented better morphological structure (132-90.5 mu m) and mechanical responses (0.451 MPa with 100 mg BG) as confirmed by SEM analysis...

Azo-Linked Porous Organic Polymers: Robust and Time-Efficient Synthesis via NaBH4-Mediated Reductive Homocoupling on Polynitro Monomers and Adsorption towards Aniline in Water
Time-efficient synthetic methods of porous organic polymers are searched in order to extend the applications of those materials. In this work, we show a robust and time-efficient synthetic method of azo-linked porous organic polymers named Azo-POPs based on a NaBH4-mediated reductive coupling polymerization on well-known polynitro monomors. Azo-POPs were found to have high Brunauer–Emmett–Teller...

【Carbohydrate Polymers-2017年春季】Antimicrobial efficiency of PAA/(PVP/CHI) erodible polysaccharide multilayer through loading and controlled release of antibiotics
The adhesion of bacteria and subsequent formation of biofilm on the surface of implants greatly affect
the long-term use of the implants. The low molar mass gentamicin (GS) cations could hardly be directly
incorporated into the multilayer films through alternately deposition with a polyanion. Herein, we have
designed and constructed a (poly(acrylic acid)/(polyvinylpyrrolidone/chitosan))...

Synthesis of Electron-Deficient Borinic Acid Polymers with Multiresponsive Properties and Their Application in the Fluorescence Detection of Alizarin Red S and Electron-Rich 8?Hydroxyquinoline and Fluoride Ion: Substituent Effects
Electron-deficient borinic acid monomers and corresponding polymers
were synthesized with different substituents via a one-pot reaction of Grignard reagents with trimethoxyborane and reversible addition?fragmentation chain transfer polymerization, respectively. Further investigations of substituent effects of borinic acid polymers (PBAs) were carried out, indicating that the thermoresponsive ...

[Polymers] Synthesis of PNVP-Based Copolymers with Tunable Thermosensitivity by Sequential Reversible Addition-Fragmentation Chain Transfer Copolymerization and Ring-Opening Polymerization
Through the reversible addition–fragmentation chain transfer (RAFT) copolymerization of 3-ethyl-1-vinyl-2-pyrrolidone (C2NVP) and N-vinylpyrrolidone (NVP), a series of well-defined P(C2NVP-co-NVP) copolymers were synthesized (Mn = ca. 8000 to 16,000 and Mw/Mn < 1.5) by using a difunctional chain transfer agent, S-(1-methyl-4-hydroxyethyl acetate) O-ethyl xanthate (MHEX). Copolymerizing kinet...

Immortal ring-opening polymerization of epsilon-caprolactone by a neat magnesium catalyst system: an approach to obtain block and amphiphilic star polymers in situ
Catalyst systems obtained from the inexpensive, ligand-free and commercially available MgnBu2 and alcohols were used for the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL) under mild conditions. The catalytic system of MgnBu2/Ph2CHOH showed very high activity as compared with the system of MgnBu2/Ph3COH, which applied a more bulky methanol derivative. Interestingly, in the pre...
