Mechanical Properties of Shape-memory Polyurethane Composites with Hindered Phenol Compounds and Silica Particles
Polyurethane is an elastomeric multi-block polymer consisting of chain molecules joined by urethane links, where the urethane hard segments act as crosslinks between amorphous polyether soft segment domains.

Shape of Fluid Vesicles Anchored by Rigid Rod
关键字：Shape,Fluid,Vesicles,Anchored,Rigid,Rod,
As a simple model of biological membranes, in recent years, tremendous interest has been focused on the polymer anchored vesicles. For many real cell membranes, the ‘ornaments‘ which anchored on membrane usually are semiflexible ...

Shape Characterization and Recognition of Cross-Section of Profiled Fibre by Microscopy and Image Analysis
关键字：Image Analysis
In order to describe the cross-section shape of profiled polyacrylonitrile fiber(PAN) in different aspects, four shape factors, i.e. Flatness (FL), Roundness (R), Concavity (CO) and Asymmetry (AS) were proposed and calculated using cross-se...
