Abstract
The formation of mesoscopic structured arrays and hierarchical patterns using colloidal-crystal-assisted imprint (CCAIP) approach, was investigated. The polymer films or multilayered hybrid films were imprinted at a temperature above the glass-transition temperature of desired polymer using three-dimensional colloidal crystals. Two-dimensional patterns were achieved on substrates after three-dimensional colloidal crystals were removed by etching or ultrasonication. The results show that unwanted defects could be eliminated by controlling the formation of colloidal crystals and imprint process during the CCAIP procedure.
