One-step and eco-friendly modification of cellulose membranes by polymer grafting

摘要: The increasing environmental awareness has stimulated the use of bio-based materials and processes. As an affordable sustainable biopolymer, cellulose is ideal engineering material. Beyond paper, finds applications in many areas such as composites, electronics drug delivery. To fulfil these new functions, needs to acquire properties, which commonly done by graft polymerization acrylic compounds. While modification usually performed through complex expensive procedures, diazonium-based polymer grafting procedure presented here was water, at room temperature, a short single step. Cellulose sheets have been successfully grafted with several polymers, first globally dipping then locally inkjet printing. process developed herein simple, eco-friendly mostly time cost-saving. More generally, it powerful tool for easy, robust patterned copolymerization various monomers even monomers.
