摘要：
The disclosure provides a composition comprising a modified cellulosic surface having aliphatic fatty acid molecules and amine-silica particles that are covalently bonded to cellulose fibers of the cellulosic surface. Also disclosed is a composition comprising a modified cellulosic surface including low surface energy molecules and amine functionalized nanotubes decorated with silica nanoparticles that are covalently bonded to cellulose fibers of the cellulosic surface. Also disclosed is a process for increasing hydrophobicity of a cellulosic surface. Also disclosed is a process for increasing hydrophobicity and surface roughness of a cellulosic surface. Also disclosed are products comprising the compositions and modified cellulosic surfaces of the present invention.
