摘　　要：基于麦饭石的功能,研究加载纳米麦饭石的再生丝素蛋白多孔材料的远红外升温与抗菌性能。研究结果表明:加载纳米麦饭石的多孔材料的升温速率均高于纯丝素多孔材料,尤以短时间升温速率更显著。在远红外灯光照射5 min时,加载10%纳米麦饭石多孔材料的升温速率比纯多孔材料的升温速率提高1倍以上,当多孔材料的温度不再变时,纯多孔材料和加载10%纳米麦饭石多孔材料的升温率分别为55.78%和83.41%。加载纳米麦饭石的多孔材料对大肠杆菌和金黄色葡萄球菌具有较好的抗菌性能,抑菌率分别为95%和98%左右。Based on the functions of maifan stone,this paper studied the far infrared heating and antibacterial property of regenerated silk fibroin porous materials loading nanometer maifan stone. The experimental results showed that： the heating rates of silk fibroin porous materials with nanometer maifan stone were all higher than that without maifan stone,especially the short time heating rate. After irradiation for 5 min,the heating rate of porous material with 10% nanometer maifan stone increased more than one times than pure porous material. The final heating rates of pure porous material and 10% nanometer maifan stone loaded porous material were 55. 78% and 83. 41%,respectively. The antibacterial properties on Escherichia coli and Staphylococcus aureus of nanometer maifan stone loaded silk fibroin porous materials were better than those with no nanometer maifan stone,which were about 95%and 98%.
