One of the main modification methods is to introduce various functional groups through the graft modification of cellulose-based materials to adapt to different needs.
纤维素纤维在单体的链式聚合反应中，易发生接枝单体进入纤维内部引发的纤维溶胀，破坏纤维结构并损伤纤维强度。为保证纸基材料的特性和强度，并降低引发剂及单体在反应体系中的无效接枝和浪费，在纤维素基材料中加入能够负载引发剂的纤维材料(如纳米纤丝、微纤化纤维素、无机纤维或芳纶纤维等)，使其吸附覆盖在纤维材料上，从而将自由基聚合反应主要限制在含有引发剂的载体及纸基材料的表面。In the chain polymerization reaction of monomers in cellulose fibers, it is easy to cause fiber swelling caused by grafted monomers entering the fiber, destroying the fiber structure and impairing the fiber strength. In order to ensure the characteristics and strength of paper-based materials, and reduce the ineffective grafting and waste of initiators and monomers in the reaction system, fiber materials capable of loading initiators (such as nanofibrils, microfibers, etc.) are added to cellulose-based materials. cellulose, inorganic fiber or aramid fiber, etc.) to adsorb and cover the fiber material, so that the free radical polymerization reaction is mainly limited to the carrier containing the initiator and the surface of the paper base material.
选用Fenton试剂(Fe2++H2O2)作为引发剂，廉价易得且反应以水为介质，条件温和、清洁环保，可适用于工业大规模使用和生产。铁离子的载体选用具有较大比表面积和丰富的表面羟基(-OH)的纤维等材料，可以通过调整载体表面暴露的羟基数量或反应能力(如载体纤维的打浆度、细纤维化程度等)，来控制自由基聚合反应中引发位点的数量及功能性单体的接枝率，调配纸基功能材料的效果。Fenton's reagent (Fe 2+ +H 2 O 2 ) is selected as the initiator, which is cheap and easy to obtain, and the reaction uses water as the medium, the conditions are mild, clean and environmentally friendly, and it is suitable for large-scale industrial use and production. The carrier of iron ions is selected from materials such as fibers with a large specific surface area and abundant surface hydroxyl groups (-OH), which can be adjusted by adjusting the number of hydroxyl groups exposed on the surface of the carrier or the reaction ability (such as the beating degree of the carrier fiber, the degree of fibrillation, etc.) , to control the number of initiation sites and the grafting rate of functional monomers in the radical polymerization reaction, and to adjust the effect of paper-based functional materials.
适用于多种纤维素基材料例如各种滤纸(选择性滤纸)，包装纸，阻燃纸以及各种具有表面改性需要的纸张及其制品。It is suitable for a variety of cellulose-based materials such as various filter papers (selective filter paper), packaging paper, flame-retardant paper, and various papers and their products that require surface modification.
