EFFECT OF PROCESSING TECHNIC AND SEVEN HOLE HOLLOW POLYESTER FIBERS ON THE FT-IR AND MICRO-STRUCTURE OF CPE-AO 2246

Abstract

Abstract: A series of CPE-AO 2246 and SHPF/CPE-AO 2246 damping composites were prepared with chlorinated polyethylene (CPE), 2,2′-methylene-bis-(6-tert-butyl-4-methyl-phenol)(AO2246) and seven hole hollow polyester fibers( SHPF). Hydrogen bond formation and microstructure of composites were measured and investigated by means of FT-IR and SEM. The results showed that new absorption peak was formed in the 3528cm^-1 and 3505cm^-1 in CPE-AO 2246 composite which was made by hot pressing conditions of high temperature. AO 2246 crystals were seen everywhere in CPE-AO 2246 composite without hot-pressed while there were full of CPE-AO 2246 hybrids in hot-pressed CPE-AO 2246 composite; with adding SHPF, new absorption peak was formed in the 758.4cm^-1 and 775.5cm^-1 in CPE-AO 2246 composites, AO 2246 crystal significantly increased, and sub-hybrids were formed by a small amount of AO 2246 compatible with CPE. These constituted evidences of further revealing damping mechanism of the organic hybrid material.

Key words: fourier transform infrared spectrometer, reversible hydrogen bond, absorption peak, sub-hybrids
