| 摘 要： | 以天然纤维素醚衍生物羟丙基纤维素和壳聚糖为基本原料，制备了羟丙基纤维素／壳聚糖（CSPC）抗菌剂。利用傅立叶变换红外光谱（FT-IR）、热重一差热分析（TG-DSC）、静置法、最小抑菌浓度（MIC）对CSPC抗菌剂进行表征，结果表明该抗菌剂一方面具有优良的抑菌特性，且抑制真菌生长的能力强于细菌，另一方面具有对温度的敏感特性，CSPC抗菌剂耐温性可达250℃，且酸碱稳定性良好。

| Abstract: | CSPC antibacterial agent was prepared with nature cellulose ether derivatives named hydroxypropylcellulose and chitosan as raw materials. Its properties were characterized by FT-IR, TG-DSC, precipitation method and MIC. Results showed that CSPC antibacterial agent had excellent inhibition-activity and thermo-sensitive property, inhibiting the growth of fungi was better than bacterium, resistance to high temperature can reach 250℃ and stability in acid and/or alkali solutions was good. |
