Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2018 / V.30,no.3,Sept Title The Scattering Property of EVA/SiO2 Composite Film Formed Micro-aggregation Structure for Roll-to-roll Process Authors Kuk Hyun Jo, Jun Yeong Yang, Si Woo Lee, Eun Kyoung Park, Geun Seok Choi, Ki Won Song and Hyo Jung Kim* Institution/Affiliations Pusan National University Pages/Total page pp.190 ~ 198 / 9 Language Korean Abstract We fabricated high transmission and high scattering poly(ethylene-co-vinyl acetate)(EVA) films embedding SiO2 nanoparticles to improve outcoupling efficiency in organic display. The 800nm diameter SiO2 nanoparticles aggregated and formed 1.56㎛ (with ±0.853㎛ standard deviation) diameter microparticles in EVA. The total transmission of scattering film was 83.3% on Polyethylene terephthalate(PET), which was higher than reference 82.8% PET substrate. The diffuse transmission and haze of the SiO2 embedded EVA film were 76.1% and 91.4%, respectively. The optimized condition was 1:1 weight ratio of SiO2 nanoparticles to EVA in Tetrahydrofuran(THF) solution. When the ratio of SiO2 was larger than 1, the total transmission decreased by the increase in backscattering of light due to high scattering. With the optimized condition, we could succeed to fabricate a large scale film(35m in length) with a roll-to-roll process.
