面对日益严格的环保法规和市场对可持续材料的需求，纸张用生物基无氟防水防油涂层的开发成为当前的研究热点之一。文章通过在对苯二甲醛(TA)交联羧甲基壳聚糖(CCS)的体系中引入少量氧化石墨烯(GO)，并喷涂疏水纳米二氧化硅(SiO2)分散液，在牛皮纸表面构建了对水和油具有良好阻隔性能的生物基无氟防水防油涂层，并研究了GO和SiO2用量对涂布纸防水防油性能的影响。结果表明，当GO用量为CCS质量的5%、SiO2与CCS质量比为1∶1时，涂布纸的水接触角达到137.6°，Cobb 60值降至14.8 g/m2，防油等级达到12/12级。
Abstract：Due to the increasingly stringent environmental regulations and the great demand for sustainable materials, fluorine-free water-and oil-resistant coatings for paper has attracted considerable attention. In this study, a bio-based fluorine-free water-and oil-resistant coating with excellent barrier properties against water and oil was constructed on kraft paper by introducing graphene oxide(GO) into the crosslinked network of terephthalaldehyde(TA) and carboxymethyl chitosan(CCS) and spraying hydrophobic silica(SiO2). The effects of GO and SiO2 content on the barrier properties of the coated paper were investigated. The results indicated that when the GO content was 5% of the mass of CCS and the mass ratio of SiO2 and CCS was 1∶1, the water contact angle of the coated paper reached 137.6°, the Cobb 60 value decreased to 14.8 g/m2, and the kit rating achieved 12/12.
