摘 要：A series of silica nanoscale materials（NIMs） were prepared through a facile acid-base neutralization. These silica derivatives consist of a nanosilica core, a charged corana（sulfonic acid SIT） attatched to the core, and an oppositely charged canopy （PEG-substituted tertiary amines） to balance the corona. By selecting proper canopy such as surface-functionalized, silica can behave viscous liquid in the absence of any solvent at room temperature. DSC results indicated the melting temperature and glass transition of the derivatives were slightly lower than those of the neat polymer canopy, indicating strong interaction between the core and PEG-substituted tertiary amine.
