There are many properties such as hydrophobicity and anti-reflection associated with glasses with micro/nano structures on the surface. Traditional fabrication method such as laser machining, wet/dry etching are time consuming and expensive. Replica molding methods can fabricate surface micro/nano stuctures with fast speed. Among them, micro hot embossing is the most commonly used method. However, the long heating/cooling cycle and the batch-mode production prevent it from being used in mass production. In this research, a novel roller imprinting method is proposed to fabricate micro/nano structures on the surface of glass substrates. During the roller imprinting process, heating and cooling were preformed separately and the fabrication of micro/nano structures were carried out continuously. In this research, a roller imprinting facility, with induction and infrared heaters, is designed and implemented to fabricate micro/nano structures on the surface of glass substrates. Methods to increase transcription rate was investigated in this research. Nano pillars are fabricated on the surface of soda-lime glass substrate with the mold of anodic aluminum oxide. The optical performance of anti-reflection are measured. Reflection rate was reduced from 8~25% to 0.8~2.5% in the range of wavelength between 300~800 nm. It proved that glass substrate with nano pillars on the surface have anti-reflective effect. Finally, by intergrated procedure; both micro and nano structures were fabricated on the surface of soda-lime glass and hybrid micro/nano structures were fabricated successfully. The contact angle of the surface with micro/nano structures was 114°, much higher than 20° in bare glass. This study demonstrated the potential of fabricating micro/nano structures using roller hot embossing.140 bytestext/htmlen-US滾輪壓印玻璃微透鏡陣列高週波接觸角陽極氧化鋁微奈米複合結構Roller hot embossingGlassMicro les arrayHigh frequency inducedContact angleAAOMicro/Nano structurethesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/255768/1/index.html
