  • Porous and Nonporous Nano-capsule by H-bonding Self-assembly Based on hydrogen bonding poly(vinylpyrrolidone) and poly(methacrylic acid) were layer-by-layer deposited on the surface of the AgCl microcrystals or SiO2 colloidal particles in aqueous solution to construct core-shell structure particles(Figure 5). When the AgCl and SiO2 cores were removed the porous and nonporous nanocapsules were obtained respectively. After the nonporous capsules were incubated in KSCN and HNO3 mixture solution for 24 hours the capsules shrank and the pores were formed in the shell of the capsules.

    The result was published in Macromolecules 2004 37 10059-10062
