多功能壳聚糖基防油剂在防油纸中的研究进展

壳聚糖是制备纸张防油剂潜在的理想材料,但其价格高昂、吸湿性强,需通过改性赋予其"一剂多效"功能(如在防油的同时兼顾防水、抗菌或水蒸气阻隔等功能),以提高其工业应用价值.结合壳聚糖的防油机理,总结了壳聚糖基防油剂防油性能的影响因素,综述了近年来防水型、抗菌型和水蒸气阻隔型壳聚糖基防油剂的研究现状,并对壳聚糖基防油剂的未来发展方向进行了展望.

Research progress on multifunctional chitosan based oil-repellent agent as grease-proof papermaking addtive

Chitosan is a potentially ideal material for the preparation of paper oil-repellent agent. However, the chitosan is expensive and hygroscopic. On that account, it is necessary to modify the chitosan based oil-repellent agent make it multifunctional as one agent, such as taking into account the functions of water-proof, antibacterial or water vapor barrier at the same time of oil resistance, so as to improve its industrial application value. According to the grease-proof mechanism based on chitosan, the factors influencing its oil repellency performances were summarized. Subsequently, the current research status of water-proof, antibacterial and water vapor barrier chitosan based oil-repellent agent was reviewed. Finally, the development direction of chitosan based oil-proof agents was also pointed out.
