Abstract

This paper describes the manufacture of binary nanostructured films utilizing nanosphere lithography and ultraviolet (UV) roller imprinting. To manufacture the binary nanofeatured template, polystyrene nanocolloids of two distinct dimensions (900 and 300 nm) were primarily self-assembly spun coated on a silicon substrate. A roller imprinting facility equipped with polydimethylsiloxane molds and ultraviolet radiation was employed. During the imprinting procedure, the roller was steered by a motor and compressed the ultraviolet-curable polymeric layer against the glass substrate, where the nanofeatured layer was cured by the UV light source. Binary nanofeatured films were thus obtained. The influence of distinct processing variables on the imprinting of nanofeatured films was investigated. The empirical data suggested that with appropriate processing conditions, binary nanofeatured plastic films can be satisfactorily manufactured. It also demonstrated that roller imprinting combined with ultraviolet radiation can offer an easy yet effective method to prepare binary nanofeatured films, with a miniatured processing time and enhanced part quality.

Summary

Introduction

Subsiding the sizes of a substance to the nanoscale generally leads to the variation of physical/chemical properties. Nanotechnology permits the achievement of novel materials/devices with essential structural element in nanoscale and is assessed via managing at either the atomic, molecular, or supramolecular level. The unique characteristic of binary nanostructure (or micro/nanostructure) [1] has been used in photosensors (with modification of optical properties in absorption, reflection, and color), promoted Raman imaging [2], and enhanced energy storage and transformation efficiency in photovoltaics [3,4]. Material surface with managed topographic features at the micro and nanoscales has been demonstrated to influence the entire cell behavior as well as the ultimate cell/material integration [9,10]. Binary nanofeatured surface can be used to direct differentiation into a specific cell lineage in the nanoscale circumstance [11,12]. The development of manufacturing methods for binary nanofeatured surface is highly desired
