Mechanical and thermal properties of polyimide/silica hybrids with imide-modified silica network structures.

The article presents a study on the thermal and mechanical properties of polyimide/silica hybrids with imide-modified silica network structures. The researchers prepared poly(amic acid) (PAA) by reacting high-purity monomers with anhydrous dimethylacetamide (DMAc) as a solvent. They found that the increase in the spacer length reduces the size of silica domains aside from increasing the polymer content confined within the silica network.
