"In addition, it is commonly known in the art that when it is desired to form pillars on a material, the imprinting template used for imprinting is required to have holes formed therein, and when it is desired to form holes in the material, the imprinting template is required to have pillars formed thereon."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "The object of the present invention is to provide a method of nanoimprinting a piezoelectric polymeric material that can form high aspect ratio nanopillars.
"According to the present invention, there is provided a method of nanoimprinting a piezoelectric polymeric material for forming high aspect ratio nanopillars. The method includes: heating a surface of the piezoelectric polymeric material to an imprinting temperature greater than (T.sub.c-25).degree. C. and less than T.sub.c, in which T.sub.c is the Curie temperature of the piezoelectric polymeric material; and pressing the heated surface of the piezoelectric polymeric material using a nanoimprinting template having a nanopillar structure so as to form the piezoelectric polymeric material with high aspect ratio nanopillars."
