Abstract: Polymeric nanoparticle and biopolymer network are two types of nanophase materials widely used in various applications. In this project, preferential solvation of polymer molecules and strong EPD-EPA (EPD: electron pair donor; EPA: electron pair acceptor) interaction between solvent and nonsolvent molecules were found of great significance in the fabrication of surfactant free yet stable aromatic polyimide nanoparticles. The stability of the aromatic polyimide nanoparticles can be achieved by the solvation multilayer in the form of nonsolvent->solvent->aromatic polyimide (a->i? b denotes that component b is solvated by the component a). Three methods have been developed to prepared aromatic polyimide nanoparticles with different size. On the other hand, kinetics of agarose gelation has been also studied. Agarose gelation turns out to be initiated through a nucleation and growth mechanism. The quantitative understanding of the complex nucleation and growth system facilitates us to provide some guidelines for the fabrication of the second-generation nanomaterials.
