摘要: Abstract In this study, a strong and optically transparent nanopaper was fabricated from cellulose nanofibril (CNF) of corncob residues, an abundant byproduct the processing corncobs. Two processes were applied to successfully generate CNF residues. The resultant mainly consists fibers with diameter (height) about 1.0 − 5.0 nm on average. results showed that as-prepared (CNP) exhibited good strength, optical thermal properties, tensile strength fracture strain CNP being 65.3 MPa 2.3%, respectively; transmittance close 90% in visible range; highest degradation peak temperature 290 °C; water contact angle at 30 s 68.2°; A-CNP much higher properties hydrophobicity, similar ability, but slightly lower compared B-CNP. It can be seen residues are suitable choice raw material for nanopaper, is expected find applications flexible electronics energy products as those other materials used purpose.
