在光學薄膜製程中通常採取蒸鍍或濺鍍的方式,因此製程成本較高,為了降低製程成本所以可以利用光硬化樹脂來達到。本論文的研究目的為利用壓克力系的紫外光硬化樹脂製作抗眩(Anti-glare)與抗反射(Anti-reflection)薄膜,論文架構分為二個部分,第一部分為抗眩薄膜之製備,利用填充粒子的加入來產生薄膜表面的粗糙化,因而達到抗眩效果,在本論文中利用4種不同填充粒子來作比較,此即未改質黏土、有機改質黏土、聚苯乙烯(PS)及聚甲基丙烯酸甲酯(PMMA),在本研究中可以達到穿透率90%以上且具有抗眩效果之薄膜。第二部分為抗反射膜之製作,利用兩個高低折射率的材料來製作雙層抗反射膜,利用濃度與塗佈轉速的控制來達到預定膜厚,經由反射率的量測,在本研究中已可製作達到低反射率(Low reflection, LR)之雙層抗反射膜。
The aim of this dissertation is to utilize acrylic UV curable resin to fabricate anti-glare and anti-reflection thin films. The framework of this dissertation is mainly divided into two parts. First part is the preparation of anti-glare thin film. Filler particles were added to produce coarse surface of thin film which cause anti-glare effect on film surface. Four different kinds of filler particles, untreated clay, modified clay, polystyrene(PS)and polymethyl methacrylate ( PMMA), were investigated in this thesis. Thin films with high optical transmittance (>90 %) and anti-glare effect have been achieved via this simplified wet process. Second part of the dissertation is the preparation of anti-reflection film via wet process. High and low refractive indexes materials were utilized to make a double-layer film which demonstrated rather low reflectance by the measurement of reflectance. The effect of concentration and coater’s spinning speed on film thickness has been also investigated.
