Novel composite hydrogels were synthesized by grafting of acrylic acid onto pineapple peel cellulose and addition of kaolin or sepia ink in ionic liquid 1-butyl-3-methylimidazolium chloride, using potassium persulfate as a free radical initiator and N,N′-methylenebisacrylamide as a crosslinking agent. The structure and morphology of the prepared hydrogels were characterized by Fourier transform infrared...
A core–shell structure of crosslinked poly(2-hydroxyethylmethacrylate) as corona and nanocrystalline cellulose (NCC) as core was synthesized by distillation precipitation polymerization. Then, it was reacted with a chain transfer agent of S-(thiobenzoylthioglycolic) acid to obtain NCC-RA. Homopolymers of N-isopropylacrylamide (NIPAAm) and acrylic acid (AA) as temperature- and pH-sensitive materials,...
With cellulose acetate (CA) as a base material, a novel environmentally friendly carboxylate waterborne cellulose acetate (CWCA) emulsion was synthesized via the method of self-emulsification. Taking advantage of acrylic acid, hydroxyethyl acrylate as a modifier, and isophorone diisocyanate as a bridging agent, the molecular structural design of CWCA dispersion was completed successfully, and the...
