▎ 摘　　要

NOVELTY - A self-crosslinking graphene dispersant (DSiA) is a new adenine-containing silicon compound (I). USE - The new graphene dispersant is used for preparing nano carbon material dispersion liquid (claimed) used in composite materials, energy and catalysis applications. ADVANTAGE - The new, efficient graphene dispersing agent is prepared by a simple and cost-effective method. The dispersing agent is effective even when used in small dosage, has self-high-efficiency activity, and enables stable dispersion of the nano-carbon. Hence, crosslinking of the nano-carbon into a film is enabled. The presence of many nitrogen atoms in the skeleton, imparts more catalytic activity to the carbon material. The graphene dispersing concentration reaches 4 mg/ml, which is higher than the dispersing value of most of the existing dispersing agents. DETAILED DESCRIPTION - A self-crosslinking graphene dispersant (DSiA) is a new adenine-containing silicon compound of formula (I). INDEPENDENT CLAIMS are included for: 1. preparation of new self-crosslinking graphene dispersant of formula (I). 2. nano carbon material dispersion liquid which is prepared by adding the self-crosslinking graphene dispersing agent (I) into nano carbon material powder of preset mass, deionized water, followed by performing ultrasonic treatment in a water bath, and further performing ultrasonic dispersion by using an ultrasonic cell crusher to form a corresponding nano carbon material dispersion liquid. DESCRIPTION OF DRAWING(S) - The drawing shows an FT-IR spectrum of raw material adenine, GPTMS and product DSiA precursor.
