摘要

研究了由明胶、甘露聚糖和葡甘露聚糖制备的生物聚合物薄膜的光学特性。葡甘露聚糖是由一株沙门氏色孢子菌酵母菌生产的，该酵母菌是从南极洲吉林斯岛保加利亚基地地区的地衣样品中分离出来的。测定了明胶、甘露聚糖和葡甘肽在电磁波谱可见光区、近红外区和JR区的透射光谱。测定了所研究的生物聚合物水溶液的折射率和所制备的膜在两个波长下的折射率。计算了所述聚合物的液相和膜的塞尔迈耶分散系数。用阿贝折射率计研究了给定聚合物折射率的温度依赖性。

Optical characteristics of biopolymer films from gelatin, mannan, and glucomannan

This study investigates the optical characteristics of biopolymer films from gelatin, mannan and glucomannan. Glucomannan was produced from the yeast strain Sporobolomyces salmonicolor, isolated from lichem samples from the region of the Bulgarian Base on Jirings for Island, Antarctica. Transmission spectra of gelatin, mannan and glucomarinan in the visible, NIR and JR region of the electromagnetic spectrum have been taken. The refraction indices of biopolymer water solutions studied and of the films obtained from them for two wavelengths have been measured. The dispersion coefficients of Sellmeier of the film and the liquid phase of the given polymers have been calculated. The temperature dependence of refraction index of the given polymers has been studied by means of Refractometer Abbe.
