Modification of wood-based materials by atom transfer radical polymerization methods

摘要

This article presents the state-of-the-art modification of wood and wood cell wall components via atom transfer radical polymerization (ATRP). This paper primarily focuses on summarizing the ATRP techniques with an emphasis on methods carried out with diminished amounts of catalyst that were used to synthesize bioactive surfaces and functional biomaterials based on raw wood and wood cell walls components, such as a cellulose and lignin. The biocomposites have many potential applications, including stimuli-responsive drug delivery systems with controlled release, cationic gene carriers, adsorbents for removal o f pollutants, membranes with protein binding capacities, antimicrobial and low-adherent surfaces, and fibers for the textile industry. Recent advances in preparation of biopolymers indicate that ATRP, in particular procedures with low catalyst concentration, have become excellent tools for the synthesis of advanced biomaterials with a wide range o f industrial applications.
