Hydrophobic modification of starch via enzymatic grafting polymerization of fluorinated vinyl monomer.
The synthesis of starch grafted with poly (hexafluorobutyl methacrylate) (PHFBMA) was achieved using the horseradish peroxidase (HRP)/acetophenone (ACAC) green initiating system. The modified starch was characterized through FT-IR, 19F NMR, XPS and EDS to confirm the successful grafting of PHFBMA onto starch backbone. The SEM analysis revealed that the introduction of PHFBMA led to a partial disruption of the crystalline structure of starch, suggesting that PHFBMA did not undergo physical adsorption onto starch. Compared to natural starch film, the modified starch film displays a significantly enhanced hydrophobicity, which can lead to substantial improvements in both the hydrophobicity and tensile properties when applied to hydrophilic paper substrates.
期刊介绍：
Carbohydrate Research publishes reports of original research in the following areas of carbohydrate science: action of enzymes, analytical chemistry, biochemistry (biosynthesis, degradation, structural and functional biochemistry, conformation, molecular recognition, enzyme mechanisms, carbohydrate-processing enzymes, including glycosidases and glycosyltransferases), chemical synthesis, isolation of natural products, physicochemical studies, reactions and their mechanisms, the study of structures and stereochemistry, and technological aspects.
Papers on polysaccharides should have a "molecular" component; that is a paper on new or modified polysaccharides should include structural information and characterization in addition to the usual studies of rheological properties and the like. A paper on a new, naturally occurring polysaccharide should include structural information, defining monosaccharide components and linkage sequence.
Papers devoted wholly or partly to X-ray crystallographic studies, or to computational aspects (molecular mechanics or molecular orbital calculations, simulations via molecular dynamics), will be considered if they meet certain criteria. For computational papers the requirements are that the methods used be specified in sufficient detail to permit replication of the results, and that the conclusions be shown to have relevance to experimental observations - the authors'' own data or data from the literature. Specific directions for the presentation of X-ray data are given below under Results and "discussion".
