Compact Polymeric Gel and Fibers Made Therefrom

摘要

The present disclosure relates to a compact polymer gel consisting of ultrahigh molecular weight polyethylene (UHMWPE), at least one nucleator, at least one filler and at least one fluid medium. The present disclosure also provides a process for the preparation of the compact polymeric gel and fibers from the compact polymeric gel. The fibers prepared in accordance with the present process have tensile strength ranging from 2.5 to 10 GPa and tensile modulus ranging from 110 to 300 GPa.

1. A compact polymeric gel comprising:
i. ultrahigh molecular weight polyethylene (UHMWPE) in an amount ranging from 2.0 to 25.0% with respect to the total mass of the gel; ii. at least one nucleator in an amount ranging from 0.05 to 3.0% with respect to the total mass of the gel; iii. at least one filler in an amount ranging from 0.025 to 1.0% with respect to the total mass of the gel; and iv. at least one fluid medium, said gel characterized in that the UHMWPE is selected from the group consisting of entangled UHMWPE and a combination of entangled UHMWPE with disentangled UHMWPE (dis-UHMWPE), wherein the amount of dis-UHMWPE is less than the amount of entangled UHMWPE.
