Title:
GRAPHENE/POLYMER MULTI-ORIENTATION FILLING MODIFIED CHEMICAL FIBER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/047957
Kind Code:
A1
Abstract:
The present invention relates to the technical field of fiber modification, and provides a graphene/polymer multi-orientation filling modified chemical fiber and a preparation method therefor. In the present invention, graphene is coated by means of in-situ suspension polymerization, thereby greatly improving the dispersion effect of the graphene; the compatibility between the graphene and polymer microspheres is improved by utilizing a comonomer, thereby forming relatively strong interaction between the graphene and the polymer microspheres; the present invention employs a low-melting-point and high-toughness graphene/polymer microsphere oriented filling modified chemical fiber, strength and toughness of the chemical fiber can be increased simultaneously, and electrical and thermal conduction properties of a chemical fiber product are expected to be improved; oriented graphene/polymer microspheres can form a microfiber structure having a high length-to-diameter ratio in a single fiber, and the structure can inhibit formation of cracks in the radial direction (the main fracture direction of the fiber) on one hand, and can induce high orientation and crystallization of polymer molecules in a chemical fiber matrix on the other hand, so that the strength of a fiber material is increased.
