Highly Ordered Nanoring Arrays Formed by Templated Si-​Containing Triblock Terpolymer Thin Films

Abstract

In this work, the directed selfassembly of Si-​contg. triblock terpolymer chains ordered into nanoscale ring arrays has been reported. To produce long-​range ordered ring patterns, a solvent vapor annealing (SVA) methodol. was used to promote the mobility of the poly(1,​1-​dimethylsilacyclobutane)​block-​polystyrene-​block-​poly(Me methacrylate) (PDMSB-​b-​PS-​b-​PMMA or DSM) chains deposited on topog. patterned silica substrates. By using this strategy, highly ordered core​/shell cylinders with a domain orientation change induced by the film thickness were demonstrated. An effective control of the domain orientation was achieved by using a blending methodol., which revealed an efficient route to fabricate templated DSM thin films with core​/shell cylinders having a highly desired out-​of-​plane orientation both on mesas and in trenches.
