Understanding the effect of chain entanglement on the glass transition of a hydrophilic polymer
In this article, we report an interesting phenomenon of the glass transition temperature (Tg) deviation of a hydrophilic polymer. Polyacrylamide (PAL) samples with different extents of chain entanglement were prepared by spray drying and solution casting. We found that the glass transition temperature increases as the extent of chain entanglement decreases upon the sub-Tg annealing. The...

Tensile and interfacial properties of unidirectional flax/glass fiber reinforced hybrid composites
This paper studied the mechanical behaviors of unidirectional flax and glass fiber reinforced hybrid composites with the aim of investigation on the hybrid effects of the composites made by natural and synthetic fibers. The tensile properties of the hybrid composites were improved with the increasing of glass fiber content. A modified model for calculating the tensile strength was given based on t...

72. Immobilization of N/S-codoped BiOBr Nanosheets on Glass Fibers for Photocatalytic Degradation of Rhodamine B
Aiming at effectively utilizing visible light and convenient separation of the photocatalysts from the water-treatment system, the N + S-codoped BiOBr photocatalysts with a three-dimensional (3D) open porous structure and visible-light photocatalytic performance have been immobilized on the surface glass fibers (GFs) by a facile solvothermal route. The morphologies and structure of ...

Molecular Mobility and Glass Transition of Thin Films of Poly(bisphenol A carbonate)
Glass transition behavior of thin poly(bisphenol A carbonate) (PBAC) films capped between two aluminum (Al) layers is investigated by means of dielectric expansion dilatometry and dielectric relaxation spectroscopy accompanied by contact angle measurements. The thermal glass transition temperature is more or less independent of the film thickness down to 20 nm. For thickness below 20 nm, an i...

N2-Filled Hollow Glass Beads as Novel Gas Carriers for Microcellular Polyethylene
N2-filled hollow glass beads (HGB) were first used as novel gas carriers to prepare microcellular polymers by compression molding. Dicumyl peroxide was acted as crosslink agent to control the produced microcellular structure of low density polyethylene (LDPE)/HGB. The effect of temperature, pressure and the content of gel on the embryo-foaming, and final-foaming structure are investigated. ...
