Temperature dependence of surface composition and morphology in polymer blend film.
Thin films of poly(methyl methacrylate) (PMMA) and poly(styrene-ran-acrylonitrile) (SAN) blend can phase separate upon heating to above its critical temperature. Temperature dependence of the surface composition and morphology in the blend thin film upon thermal treatment was studied using in situ X-ray photoelectron spectroscopy (XPS) and in situ atomic force microscopy (AFM). It was found that i...

Composition effect on dewetting of ultrathin films of miscible polymer blend.
Two kinds of dewetting and their transition induced by composition fluctuation due to different composition in blend [poly(methyl methacrylate) (PMMA) and poly(styrene-ran-acrylonitrile) (SAN)] films on SiOx substrate at 145 C have been studied by in-situ atomic force microscopy (AFM). The results showed that morphology and pathway of dewetting depended crucially on the composition. Possible reas...

Fabrication of robust honeycomb polymer films: A facile photochemical cross-linking process
Highly ordered honeycomb films are prepared by breath-figure method using an amphiphilic diblock copolymer of polystyrene-block-polyacrylic acid (PS-b-PAA). By simply cross-linking PS matrix via deep ultraviolet (UV) irradiation, both the solvent and thermal stability of the porous films was significantly improved while retaining the three-dimensional (3D) structures. The film surface wettability ...

Rheology and Thermal Stability of Polylactide/Clay Nanocomposites. Polymer Degradation & Stability, 2006, 91, 3149-3155.
Polymer Degradation & Stability, 2006, 91, 3149-3155.
ABSTRACT: Polylactide/clay nanocomposites (PLACNs) were prepared by melt intercalation. The intercalated structure of PLACNs was investigated using XRD and TEM. Both the linear and nonlinear rheological properties of PLACNs were measured by the parallel plate rheometer. The results reveal that percolation threshold of the PLACNs is about 4...

"Casting preforms for microstructured polymer optical fibre fabrication", Optics Express, 2006, 14(9): 5541-5547
A monolithic structured polymer preform was formed by in-situ
chemical polymerization of high-purity MMA monomer in a home-made
mould. The conditions for fabrication of the preforms were optimized and
the preform was drawn to microstructure...

Time-dependent craze zone growth at a crack tip in polymer solids
By considering the polymer bulk as a linear viscoelastic body and the craze zone at crack tip as a nonlinear damage zone, the control equation for craze zone growth has been derived. It is shown that for a time-independent craze-zone stress, the craze zone would grow only if the crack-tip stress intensity factor is changed. If the crack-tip stress intensity factor remains constant during loading, ...
