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 ...

Effect of Epoxy Resin on Rheology of PC/Clay Nanocomposites. European Polymer Journal, 2007, 43, 1635-1644.
European Polymer Journal, 2007, 43, 1635-1644.
ABSTRACT:
Polycarbonate/clay nanocomposites (PCNs) were prepared by melt intercalation using epoxy resin as a compatibilizer. The intercalated structure of PCNs was investigated using XRD and TEM. The linear and nonlinear dynamic rheological properties of PCNs were measured by the use of a parallel plate rheometer. The results reveal that the prese...

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...

A Rheological Study on Kinetics of PBT Melt Intercalation. Journal of Applied Polymer Science, 2006, 99, 1865-1871.
Journal of Applied Polymer Science, 2006, 99, 1865-1871.
ABSTRACT: A multilayered sample with alternatively superposed poly(butylene terephthalate) (PBT) and non-polar polymer/clay sheets was elaborately prepared to investigate the whole hybridization process of polar polymer. The kinetics of PBT melt intercalation was studied by a rheological approach. The whole intercalation process was demonst...

Study on Rheological Behavior of PBT-Clay Nanocomposites. European Polymer Journal, 2005, 41, 2199-2207.
European Polymer Journal
ABSTRACT: Poly(butylene terephthalate)/montmorillonite composites (PBT/MMT) were prepared by melt intercalation and then investigated using X-ray diffractometer (XRD) and transmission electron microscope (TEM) as well as parallel plate rheometer. It was found that the composites had various phase morphologies with nano-scales and distinct behaviors of a percolation networ...

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, ...
