Abstract:
The present invention relates to a preparation method of para-aramid nanofibers, and belongs to the technical field of novel polymer materials. The para-aramid nanofibers prepared in the present invention have a diameter of 10-100 nm, and a length of hundreds of microns. The preparation method includes: adding a certain amount of surfactant in a PPTA low-temperature polymerization process, and controlling aggregation of PPTA molecules along with growth of a PPTA molecule chain, thereby preparing the para-aramid fibers with a uniform size and an adjustable nano-scale diameter under assistance of other means (e.g., a coagulator and high-speed shearing dispersion). The present invention is short in production process and simple in equipment, can realize stable batch production to meet needs of large-scale production of the para-aramid nanofibers, has wide application prospects and can be applied to preparing a lithium-ion battery separator, a high-performance composite material and the like.

Claim (Index 2):
The preparation method of para-aramid nanofibers according to  claim 1 , wherein the surfactants are polyoxyethylene ether nonionic surfactants, wherein the molecular weight of the polyoxyethylene ether nonionic surfactants is from 500 to 30000, and terminal groups at one end or both ends of surfactant molecules are methoxy group, hydroxyl, amino, carboxyl or siloxy.
