Abstract

Official abstract text for this publication.

A nanofiber sheet that has a high degree of transparency, a high modulus of elasticity, a low coefficient of linear thermal expansion as well as high degrees of flatness and smoothness, in particular, a nanofiber sheet produced as a uniform and flat sheet having a high optical transmittance with cellulose as the only component. This sheet has the following characteristics: Calculated for a thickness of 60 μm, the transmittance for parallel rays of light having a wavelength of 600 nm is equal to or higher than 70%; The Young's modulus measured in accordance with the JIS K7161 method is equal to or greater than 10 GPa; The coefficient of linear thermal expansion measured in accordance with the ASTM D606 method is equal to or smaller than 10 ppm/K.

First claim

Opening claim text (preview).
