柔性透明聚酰亞胺薄膜材料獲專利

   2010-11-16 IP屬地 山東
  中科院長(zhǎng)春應(yīng)化所發(fā)明的一種柔性透明聚酰亞胺薄膜材料及其制備方法日前獲得國(guó)家知識(shí)產(chǎn)權(quán)局授權(quán)。


  聚酰亞胺具有很多特殊性能,如溶解性明顯提高,顏色淺的同時(shí)還保留高的熱穩(wěn)定性和良好的機(jī)械強(qiáng)度,全可見光光線透過率達(dá)到90%。該專利發(fā)明的柔性透明聚酰亞胺薄膜材料薄膜有良好的透光性,厚度在25微米對(duì)500nm以上波長(zhǎng)光線透過率大于90%;有良好的耐熱性,薄膜的玻璃化轉(zhuǎn)變溫度在250℃以上;薄膜表面光潔、平整,可滿足柔性平板顯示和太陽(yáng)電池襯底的聚合物薄膜使用要求。
