NANOPARTICLES AND FABRICATION THEREOF

摘要

Creation of nanoparticle structures in two and three dimensions is advantageous in providing a number of functions such as in relation to catalytic, optical, electronic and magnetic propertied and other actions. Fabrication of such structures poses a considerable technical challenge. A block copolymer pair is used as a matrix to spatially organizes and aligns loaded inorganic materials in the form of nanoparticles. The inorganic precursors are selectively incorporated to a specific block of a di or tri block copolymer so that through solvent evaporation, reduction and mechanical working such as LAOS the orientation and positioning of the block copolymers nanoparticles are obtained into a desired structure.
