摘要

本研究通过旋涂法制备了纤维素纳米晶(CNC)增强环烯烃共聚物(COC)复合膜。为将其应用于透明柔性基底,研究了复合膜的物理特性,如透明度、热膨胀系数(CTE)、热性能和抗划伤性。COC 具有较高的光学透明度,因此被用作基体,而 CNC 则被用作填料,以降低 CTE 并提高热性能和机械性能。随着 CNC 添加量的增加,拉伸强度和弹性模量显著提高。此外,CNC/COC 薄膜的透明度高达 85%。

Enhanced thermal, mechanical, and optical properties of cellulose nanocrystal embedded cyclic olefin copolymer composite film

Enhanced thermal, mechanical, and optical properties of cellulose nanocrystal embedded cyclic olefin copolymer composite film

Enhanced thermal, mechanical, and optical properties of cellulose nanocrystal embedded cyclic olefin copolymer composite film

In the current study, cellulose nanocrystal (CNC) reinforced cyclic olefin copolymer (COC) composite film was fabricated via spin-coating. For the application to the transparent and flexible substrate, the physical characteristics of the composite film were investigated, such as transparency, coefficient of thermal expansion (CTE), thermal properties and scratch resistance. COC was used as a matrix due to its high optical transparency, and CNC was utilized as a filler to lower CTE and enhance the thermal and mechanical properties. As the CNC loading increased, the tensile strength and elastic modulus increased significantly. In addition, the CNC/COC film exhibited a high transparency of 85%.
