Development and application of nano-porous fiber by crazing

【Supercategory：1. Fiber/polymer materials Category：1.2 Synthetic fiber/polymer materials Subcategory：1.2.1 Petroleum derived fiber/polymer materials】

　We have developed high functional polymers of a specific nano-porous phase. The porous phase was called a craze that was generated by simple mechanical technique. Crazing of polymer materials is a sign of early fracture that was observed a whitening of plastics materials by the bending or poor solvent. These crazing processes were related to the molecular structure, which were a flexibility of a coiled molecular chain and an entanglement molecular weight. We have reported self-oscillation of craze bands on polymer films by the periodic stress concentration of the combination of bending and tensile stress.
