中文摘要: |
采用胶乳共混法,分别以引发剂过氧化苯甲酰(BPO)、过二硫酸钾(KPS)、偶氮二异丁腈(AIBN)、硫黄体系(VS)为引发剂,制备马来酸酐酰化壳聚糖(MCS)/天然橡胶(NR)复合材料。试验结果表明:KPS和VS引发的MCS/NR复合材料凝胶较少;VS引发的MCS/NR复合材料的物理性能比过氧化物预硫化MCS/NR复合材料大幅提高;MCS/NR复合材料的亲水性、耐热性能和抗菌性能与NR相比明显提高,有望作为制备医用NR制品的材料。 |
英文摘要: |
The maleoyl chitosan(MCS)/natural rubber(NR) composite was prepared through latex blending method with the initiators benzoyl peroxide(BPO),potassium peroxodisulfate(KPS),azobisisobutyronitrile(AIBN) and sulfur system(VS). The test results indicated that the MCS/NR composite materials initiated by KPS and VS had less gel;the physical properties of MCS/NR composite initiated by VS increased greatly than those of MCS/NR composite pre-vulcanized by the peroxide. The hydrophilicity,heat resistance and antibacterial property of MCS/NR composite were obviously improved compared with NR. It was expected to be used in fabricating NR products for medical care application. |
