摘要

壳聚糖基共混物因其优异的性能和在各个领域的潜在应用而受到众多研究者的关注。壳聚糖共混物的先进开发融合了共混材料的科学技术。本实验报道了壳聚糖和琼脂共混物(CCA)的化学混合这些材料在不同的组成。采用差示扫描比色仪(DSC)和热重分析(TGA)对制备的共混物进行了热研究。热研究表明，共混物的最低降解温度可能归因于CAA共混物在特定组成下的部分混溶，以及壳聚糖与琼脂之间的单玻璃化转变温度(Tg)的混溶。利用傅里叶变换红外(FT-IR)仪器研究了样品共混物的键合性质。本研究揭示了壳聚糖与琼脂之间的相互作用是部分混溶的。形态学研究表明，CAA共混物中有少量聚集颗粒，表明其具有部分混相性。还观察到共混物组成的均匀性和氢键类型的特定分子间相互作用。

Thermal and morphological studies of chitosan and agar-agar blends

Many researchers are attracted to Chitosan based blends due to its properties and potential applications in various fields. The advanced development of Chitosan blends integrates the science and technology of blended materials. The present experimentation is reporting the preparation of Chitosan and Agar-Agar blends (CCA) by chemical mixing of these materials at different compositions. The thermal studies of the prepared blends were studied by differential scanning colorimeter (DSC) and thermogravimetric analysis (TGA) tools. Thermal studies reveal that the lowest degradation temperatures of blends might be attributed to the partial miscibility of CAA blends at particular composition and miscibility due to single glass transition temperature (Tg) between Chitosan and Agar-agar. Bonding nature of sample blends were carried out by Fourier transform infrared (FT-IR) instrumentation. This study reveals the interaction between Chitosan and Agar-agar is partial miscibility. Morphological study reveals that a few aggregated particles, which suggest the partial miscibility of CAA blends. Homogeneity of blend compositions and specific intermolecular interactions of hydrogen bonding type is also observed.
