| titleOfInvention | Preparation method of chlorosilane modified graphene oxide/silicon dioxide heat-insulation composite material |
| abstract | The invention belongs to the field of building thermal insulation materials, and discloses a preparation method of a chlorosilane modified graphene oxide/silicon dioxide aerogel composite thermal insulation material, which comprises the following steps: preparing a graphene oxide solution; preparing chlorosilane modified graphene oxide; preparing chlorosilane modified graphene oxide/silicon source sol; preparing modified graphene oxide/silicon dioxide gel; and (3) preparing the modified graphene oxide/silicon dioxide aerogel. According to the invention, the high reaction activity between tetrachlorosilane and hydroxyl is utilized to carry out surface chemical modification on graphene oxide, and the obtained chlorosilane-modified graphene oxide has good dispersibility in an alcohol/water mixed solution of a silicon source precursor. In addition, chlorosilane on the surface of the modified graphene oxide can be used as a reaction active point, so that a strong Si-O-Si chemical bond connection is formed between the modified graphene oxide and a hydrolysate of a silicon source, sufficient cross-linking points between the graphene oxide and a silicon dioxide three-dimensional network are ensured, and an effective mechanical enhancement effect is achieved. |
