壳聚糖涂布可显著提高纸张的光泽度和氧气阻隔性能。其中,纸张纵向光泽度随壳聚糖用量的增加而增加。以壳聚糖为涂料,80g/m2的复印纸上的涂布量为6.9g/m2时,可获得氧渗透值为1.1cm3/m2的纸张。同时,壳聚糖对纸张机械性能也有积极的影响,但并不显著。壳聚糖涂布可使纸张的水蒸汽渗透性能增加。将壳聚糖溶解于1.6%,3.2%,和6.4%的乳酸中,对枯草芽孢杆菌具有一定的抗菌活性。然而溶解在醋酸和丙酸中(1.6%,3.2%,和6.4%)并未产生明显的活性。Nisin(0.08g/L)的加入并没有提高壳聚糖涂料的抗菌性。
Chitosan coating can significantly improve paper gloss and oxygen barrier properties. Among them, the paper longitudinal gloss increases with the amount of chitosan. With chitosan as a coating material, a paper having an oxygen permeation value of 1.1 cm 3 / m 2 can be obtained when the coating amount on the 80 g / m 2 copy paper is 6.9 g / m 2. At the same time, chitosan also has a positive effect on the mechanical properties of the paper, but it is not significant. Chitosan coating can increase the water vapor permeability of paper. Chitosan dissolved in 1.6%, 3.2%, and 6.4% of lactic acid, Bacillus subtilis has a certain antibacterial activity. However, dissolution in acetic acid and propionic acid (1.6%, 3.2%, and 6.4%) did not produce significant activity. The addition of Nisin (0.08 g / L) did not improve the antibacterial properties of the chitosan coating.
