Core-shell flame retardant/graphene oxide hybrid：a self-assembly strategy towards reducing fire hazard and improving toughness of polylactic acid
Here, we report a green and facile method for the synthesis of biobased flame retardant/graphene oxide hybrid (GOH) as a multifunctional flame retardant for polylactic acid (PLA) through organic-solvent-free self-assembly. The electrostatic interactions deposited the polyethylenimine (PEI) and biobased polyelectrolyte (BPE) coating on the surface of ammonium polyphosphate (APP) in water, which gav...

Novel phosphoric acid (PA)-poly(ether ketone sulfone) with flexible benzotriazole side chains for high-temperature proton exchange membranes
Poly(ether ketone sulfone)s with functionalized benzotriazole side chains are simply designed and successfully obtained by the copolycondensation of 4,4-difluorodiphenylsulfone, 4,4’-dihydroxydiphenylamine and a benzotriazole-based difluoro compound. The resulting polymers are identified by Fourier transform infrared spectroscopy and nuclear magnetic resonance, and the results are consistent wi...

JMCA-Tannic acid encountering ovalbumin: a green and mild strategy for superhydrophilic and underwater superoleophobic modification of various hydrophobic membranes for oil/water separation
Superhydrophilic membranes have attracted significant attention due to their desirable anti-oil-fouling performance for oil/water separation. Although many strategies have been developed to prepare superhydrophilic membranes, few of them are completely green and can be applied for various highly hydrophobic materials. Since most of the widely used membrane materials are usually hydrophobic, an env...

Preparation of thermoresponsive Fe3O4/P(acrylic acid–methyl methacrylate- N-isopropylacrylamide) magnetic composite microspheres with controlled shell thickness and its releasing property for phenolphthalein
In this work, Fe3O4/P(acrylic acid–methyl methacrylate–N-isopropylacrylamide) (Fe3O4/P(AA–MMA–NIPAm)) thermoresponsive magnetic composite microspheres have been prepared by controlled radical polymerization in the presence of 1,1-diphenylethene (DPE). The shell thickness of thermosensitive polymer (PNIPAm), which was on the surface of the microspheres, can be controlled by using DPE method. Th...

Selective visualization of endogenous hypochlorous acid in zebrafish during lipopolysaccharide-induced acute liver injury using a polymer micelles- based ratiometric fluorescent probe
The development of effective method for monitoring of endogenous hypochlorous acid (HClO) in vivo is of great significance for early diagnosis of lipopolysaccharide (LPS) induced acute liver injury. Herein, we report a polymer micelles-based ratiometric fluorescent probe (PM) based on the combination of intramolecular charge transfer (ICT) mechanism and fluorescence resonance energy transfer (FR...

Preparation of Highly Cross-linked Hydrophilic Porous Microspheres Poly(N,N’-methylenebisacrylamide) and Poly(N,N’-methylenebisacrylamide-co-acrylic acid) with an Application on the Removal of Cadmium
An effective polymerization system was developed for the synthesis of highly-crosslinked hydrophilic monodispersed microspheres with both the micropores
and mesopores inside. A series of poly(N,N’-methylenebisacrylamide) (PMBA)
microspheres with the diameters ranging from 100 to 300 nm were synthesized by
distillation precipitation polymerization with N,N-dimethylacetamide (DMAC) as th...

From celluloses nanospheres, Nanorod to nanofibers: Various Aspect Ratios Induced Different Nucleation/Reinforcing Effect on Polyactic acid for Robust-barrier Food Packaging
The traditional approach toward improving crystallization rate, mechanical and barrier property of poly(lactic acid) (PLA) is the incorporation of nanocelluloses (NCs). Unfortunately, little study was focused on the influence of differences in NC morphology and dimension on the PLA property enhancement. Here we unveil the preparation of cellulose nanospheres (CNS), rod-like cellulose nanocrystals ...

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 ...

Cellulose nanocrystals/polyethylene glycol as bifunctional reinforcing/compatibilizing agents in poly(lactic acid) nanofibers for controlling long-term in vitro drug release
Electrospun poly(lactic acid) (PLA) nanofibers would seem be poor carriers for drug delivery due to their hydrophobicity, high crystallinity, weak mechanical strength and burst drug release due to poor compatibility with hydrophilic drugs. Thus, in this work, cellulose nanocrystals (CNC) as reinforcing agents and polyethylene glycol (PEG) as a compatibilizer to increase dispersion of both CNC and ...
