Intercalation of phosphotungstic acid into layered double hydroxides by reconstruction method and its application in intumescent flame retardant poly (lactic acid) composites
Phosphotungstic acid is a typical kind of superior catalysts, and it is hardly to intercalate into the layered double hydroxides (LDH) by ion-exchange process because of its low negative charge. In this work, a phosphotungstic acid intercalated MgAl-LDH (PWA-LDH) was prepared by reconstruction method, and it was then introduced into poly (lactic acid) (PLA) resin in association with intumescent fl...

One-pot facile fabrication of graphene-zinc oxide composite and its enhancedsensitivity for simultaneous electrochemical detection of ascorbic acid,dopamine and uric acid
Reduced graphene oxide-zinc oxide (RGO–ZnO) composite was facilely fabricated by a spontaneous reduction of graphene oxide via zinc slice in one-pot approach at room temperature, and used to modify glassy carbon electrode (GCE) for developing of electrochemical biosensor (RGO–ZnO/GCE). The as-prepared RGO–ZnO was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), ...

(Ind. Eng. Chem. Res. )2, 5-Furandicarboxylic acid and Itaconic acid Derived Fully Bio-based Unsaturated Polyesters and their Cross-linked Networks
A range of fully biobased unsaturated polyesters (bio-UPs) derived from 2,5-furandicarboxylic (FDCA),itaconic acid (IA), succinic acid (SA), and 1,3-propanediol (PD) were obtained via direct polycondensation. The chemical structures of the bio-UPs were identified by Fourier transfrom infrared spectroscopy and 1H NMR before they were cured together with a biobased, nonvolatile reactive diluent, g...

(ACS Sustain. Chem. Eng.) Itaconic acid as a green alternative to acrylic acid for producing soybean oil-based thermoset: synthesis and properties
In this paper, itaconic acid was monomethylated with methanol to produce monomethyl itaconate, and then monomethyl itaconated epoxidized soybean oil (IESO) was obtained by melt ring-opening esterification of monomethyl itaconate with ESO. For comparison, acrylated epoxidized soybean oil (AESO) was also synthesized from ESO and acrylic acid with the same synthetic method. The chemical structures ...

Poly(L-lactic acid)/SiO2 Nanocomposites via In situ Melt Polycondensation of L-Lactic Acid in the Presence of Acidic Silica Sol： Preparation and Characterization
In situ melt polycondensation of L-lactic acid (LLA) in the presence of acidic silica sol (aSS) is proposed for the first time to prepare PLLA/SiO2 nanocomposites. The SiO2 nanoparticles were readily dispersed in LLA monomer, which has similar polarity and hydrophilicity to the silica sol medium. During the polycondensation process, both the matrix and the surface of SiO2 nanoparticles changed fro...

Grafting of telechelic poly(lactic-co-glycolic acid) onto O2 Plasma Treated Polypropylene Flakes
关键字：polypropylene; telechelic poly(lactic-coglycolic acid); oxygen plasma; grafting
In this work, we described a facile approach to preparing polypropylene (PP) surface functionalized with telechelic poly(lactic-co-glycolic acid) (HOPLGA-COOH). The PP flakes were first treated with oxygen plasma and then grafted with different molecular
weight PLGA (Mw ? 50, 100, and 300 K) in dry dichloromethane solution with the addition of phosphorus pentachloride (PCl...

Fabrication of a detection platform with boronic acid containing zwitterionic polymer brush
关键字：atom transfer radical polymerization (ATRP), zwitterionic-based materilals, boronic acid (BA), antibody immobilization, immunoassay
Development of technologies for biomedical detection platform is critical to meet the global challenges of various disease diagnoses, especially for point-of-use applications. Because of its natural simplicity, effectiveness, and easy repeatability, random covalent-binding technique is widely adopted in antibody immobilization. However, its antigen-binding capacity is re...
