Raspberry-like Polymer/Silica Core-Corona Composite by Self-assemble Heterocoagulation Based on A Hydrogen-bonding Interaction
Raspberry-like poly(ethyleneglycol dimethacrylate-co-4-vinylpyridine)/silica (poly(EGDMA-co-VPy)/SiO2) core-corona composite was prepared by a self-assemble heterocoagulation based on a hydrogen-bonding interaction between the pyridyl group of poly(EGDMA-co-VPy) core
and the active hydroxyl group of silica corona. The raspberrylike composite was stable near the neutral environment with pH ranging ...

Enhancing water retention and low-humidity proton conductivity of SPEEK composite membrane enabled by the polymer-microcapsules with controllable hydrophilicity-hydrophobicity
Four kinds of polymer microcapsules (PMCs) with different hydrophilicityehydrophobicity are synthesized via distillationeprecipitation polymerization (polymer microcapsules form by self-crosslinking of monomers/crosslinkers in this process) and incorporated into sulfonated poly(ether ether ketone) (SPEEK) matrix to prepare composite membranes. To improve the water retention of the PMCs, the hydrop...

Preparation and Properties of Soapless Poly(Styrene-Butyl Acrylate-Acrylic Acid)/SiO2 Composite Emulsion
Soapless emulsion polymerization of styrenebutyl
acrylate-acrylic acid was carried out using single or
combined polymerizable emulsifiers, such as hydroxypropyl
methacrylate sodium sulfate (HPMAS), sodium vinyl
sulfate, and vinyl alkylphenol polyether sulfates (NRS-10),
in the presence of colloidal nano-SiO2 solution in order to
obtain films with high degree of hardness and water-resistance.
Monom...
