查询词典 high-energy particle

Nanoparticle of an appropriate proportion were homogeneously dispersed in the PI matrix, and the interfacial adhesion between the matrix and the nanoparticle was hence strong owing to the high specific surface area and reactivity of the nanoparticle. Subsequently, the molecular chains of PI attained unchanged or even increased interaction at a proper mass fraction of the nanometer particle, which contributed to improve the wear-resistance of the nanocomposites.

Compared with other methods, the present solvent thermal method can produce ITO nano-powders with high purity and uniform particle size. The manipulation is very simple and convenient and no calcination process is needed. The reaction temperature can be as low as 190 ℃, which is by far the lowest temperature in ITO nano-powder preparation. The sample also gives a good dispersion property benefited from the unique solvent thermal reaction environment.
