Abstract

The invention provides an in-situ polymerization modified graphene and polyester composite chip as well as a preparation method and an application thereof. The composite chip is prepared from components in percentage by mass as follows: 50%-80% of PTA (purified terephthalic acid), 10%-40% of ethanediol, 0.1%-10% of graphene, 0.1%-1% of a modifier and 0.6%-1% of a catalyst. The in-situ polymerization modified graphene and polyester composite chip has excellent antibacterial, anti-mite, far-infrared and anti-ultraviolet properties, bacteriostasis rate of escherichia coli, staphylococcus aureus and candida albicans reaches 99.9%, anti-mite rate is up to 97.3%, far-infrared temperature rise reaches 0.88, far-infrared radiation temperature rise is up to 3.3 DEG C, a UPF (ultraviolet protectionfactor) is up to 218, and functionality is good. Besides, the prepared in-situ polymerization modified graphene and polyester composite chip is more uniform, spun filaments or short fibers have no chromatic aberration, furthermore, the technology is simple and easy to operate, and the composite chip is low in cost, high in economic benefit and suitable for large-scale industrial production.
