An efficient and simple way to generate “clickable” cellulose modules called alkyne-functionalized cellulose fibers (ACFs) for click reaction was presented. This method is only based on one step reaction: propargyl methacrylate (PMA) with pendant alkynyl groups was grafted onto the surface of cellulose fibers (CFs) using ceric ammonium nitrate as the initiator in aqueous medium. This has been providing...
Polyaniline/cellulose fibers (PANI/CFs) composite prepared by heterogeneous in situ polymerization of aniline (ANI) in the presence of cellulose fibers offered a new preparation approach for flexible paper-based electrodes. However, one problem was the undesirable and inevitable polymerization of aniline in the solution. It reduced the utilization efficiency of aniline, and therefore decreased the...
The degree of molecular contact, i.e. the contact area on the nanometer scale, between paper fibers is crucial for the van-der-Waals and hydrogen bond adhesion between the fibers and thus for the fiber-fiber bond strength. We apply Förster resonance energy transfer (FRET) to investigate the degree of contact in the distance range of 1–10 nm between pulp fiber bonds and between thin films. The FRET...
