Method for Manufacturing Polyimide Aerogels cross-linked with amino-functionalized hollow mesoporous silica particles |
| abstract |
The present invention relates to a process for preparing polyimide aerogels containing hollow mesoporous silica particles whose surface is modified with amine groups, comprising the steps of: preparing hollow mesoporous silica particles; Modifying the surface of the hollow mesoporous silica particles with an amine group using an alkoxysilane; Synthesizing a polyamic acid precursor by reacting an aromatic dianhydride with an aromatic diamine in an organic polar solvent; Preparing a hybrid precursor by introducing hollow mesoporous silica particles having the surface modified with an amine group into the polyamic acid precursor; Preparing an imidization reaction on the hybrid precursor to produce a polyimide gel; Replacing the polar solvent with a non-polar solvent; And drying the polyimide gel to form an aerosol through carbon dioxide supercritical drying. The present invention also relates to a method for producing a polyimide aerogel including hollow mesoporous silica particles modified with a surface amine group. |
