【摘要】:散射偏光片是一種外觀半透明略帶霧度狀態(tài)的新型光學(xué)功能薄膜材料。當(dāng)自然光入射,一半光透射,一半光散射。這種散射偏光片在透明投影屏幕上具有應(yīng)用前景,但還沒(méi)有實(shí)現(xiàn)產(chǎn)業(yè)化。本文采用干法拉伸聚乙烯醇摻雜液晶(PVA∶LC)制備散射偏光片。首先,配制聚乙烯醇摻雜液晶水溶液乳膠,在平板玻璃上通過(guò)流延晾干成膜;然后采用小型拉伸機(jī),邊烘烤加熱邊拉伸至原長(zhǎng)的4倍左右,制備出散射偏光片樣品;最后,通過(guò)實(shí)驗(yàn)測(cè)試得出樣品的透光率40%,偏振度57%。以樣品作屏幕觀察投影效果,結(jié)果顯示投影偏振光與樣品透光軸正交背投影效果最好。本文對(duì)于實(shí)現(xiàn)散射偏光片的產(chǎn)業(yè)化研究具有重要參考意義。
[Abstract]:Scattering polarizer is a kind of translucent and slightly foggy optical functional thin film material. When natural light is incident, half of the light is transmitted and half of the light is scattered. This kind of scattering polarizer has the application prospect on the transparent projection screen, but has not yet realized the industrialization. In this paper, a scattering polarizer was prepared by dry stretching polyvinyl alcohol doped liquid crystal (PVA: LC). First, we prepare poly (vinyl alcohol) -doped liquid crystal aqueous emulsion, which is used to dry film on flat glass, and then prepare scattering polarizer by baking, heating and drawing to about 4 times the original length by using a small drawing machine. Finally, The light transmittance of the sample is 40 and the polarization degree is 57. The projection effect was observed by using the sample as the screen. The results showed that the projection polarized light had the best effect on the orthogonal projection between the projective polarized light and the transparent axis of the sample. This paper has important reference significance for realizing the industrialization of scattering polarizer.
