Title:
CARBON NANOTUBE COMPOSITE HYDROGEL USED FOR TRITIUM PROTECTION FILTER, AND METHOD FOR PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/101129
Kind Code:
A1
Abstract:
Provided is a carbon nanotube composite hydrogel used for a tritium protection filter, and a method for preparation thereof; the carbon nanotube composite hydrogel comprises a carbon nanotube and a hydrogel; acrylic acid is radiation-grafted onto the carbon nanotube, and the carbon nanotube and hydrogel are composited together. The preparation method uses two-step irradiation; in the first step, irradiation is used to graft acrylic acid to the wall of a carbon nanotube, and in the second step, irradiation is used to uniformly composite a gel and the carbon nanotube.
