▎ 摘　　要

NOVELTY - Preparing graphene oxide aerogel comprises preparing first solution containing modified cotton fibers and graphene oxide and second solution containing nano tourmaline, mixing the first solution and second solution, then dispersing, introducing clean air into the dispersed solution, and adding alkali to adjusting the pH value to 10, transferring to a sealed condition and treating at 180degrees Celsius for 10 hours to obtain reactant, and freeze-drying the reactant to obtain final product. USE - The graphene oxide aerogel is useful in wear-resistant electrothermal fabric and electric heating equipment for generating electrothermal function (all claimed), and in mattress fabrics. ADVANTAGE - The graphene oxide aerogel: produces electrothermal fabric which has excellent electric heating performance, fast heating, low electric heating power, low energy consumption, and long-lasting electric heating effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: 1. graphene oxide aerogel obtained by above method; and 2. electrothermal fabric comprising fireproof outer layer, graphene oxide aerogel layer and waterproof inner layer that are stacked. The graphene oxide aerogel layer is made of the graphene oxide aerogel.
