However, it is unable to withstand the influence of water vapor. The water vapor transmission rate (WVTR) of a CNF film was as high as 5088 g/m2·24h and 332 g/m2·24h at 38°C (90% RH) and 25°C (50% RH), respectively. To reduce the WVTR, a coating agent comprised of acrylated epoxidized soybean oil (AESO) and 3-aminopropyltriethoxysilane (APTS) was applied onto the CNF film using a rod coater. The effect of the APTS content on the coating property was investigated and the WVTR was reduced by 66.3% at 38°C (90% RH) and 58.5% at 25°C (50% RH) when the coat weight was 1 g/m2. Moreover, the coated CNF film was highly hydrophobic along with good transparency.
