β-环糊精(β-CD)作为淀粉的衍生物,具有天然、无毒、环保、价格低廉等优点,越来越受到研究者的关注。采用马来酸酐(MA H )对β-CD 进行改性,得到可聚合单体(β-CD-MAH),采用过硫酸铵(APS)/亚硫酸氢钠(SBS)氧化-还原体系引发单体3-(4’-乙烯基苄基)-5,5-二甲基海因(缩写为 VBDMH )与其共聚,成功制备β-CD基卤胺化合物抗菌共聚物(缩写为β-CD-MAH-VBDMH),并采用固体13 C 核磁和红外光谱图表征了其化学结构。将抗菌剂β-CD-MAH-VBDMH和乙酸纤维素(CA)混合,利用静电纺丝技术,制备具有抗菌功能的纳米纤维,并采用SEM对纳米纤维进行了表征,确定静电纺丝的最佳工艺。碘量滴定法滴定的最佳工艺条件下纳米纤维的氯含量表明,所制得的纳米纤维具有很好的抗菌性能。
β-環糊精(β-CD)作為澱粉的衍生物,具有天然、無毒、環保、價格低廉等優點,越來越受到研究者的關註。採用馬來痠酐(MA H )對β-CD 進行改性,得到可聚閤單體(β-CD-MAH),採用過硫痠銨(APS)/亞硫痠氫鈉(SBS)氧化-還原體繫引髮單體3-(4’-乙烯基芐基)-5,5-二甲基海因(縮寫為 VBDMH )與其共聚,成功製備β-CD基滷胺化閤物抗菌共聚物(縮寫為β-CD-MAH-VBDMH),併採用固體13 C 覈磁和紅外光譜圖錶徵瞭其化學結構。將抗菌劑β-CD-MAH-VBDMH和乙痠纖維素(CA)混閤,利用靜電紡絲技術,製備具有抗菌功能的納米纖維,併採用SEM對納米纖維進行瞭錶徵,確定靜電紡絲的最佳工藝。碘量滴定法滴定的最佳工藝條件下納米纖維的氯含量錶明,所製得的納米纖維具有很好的抗菌性能。

As one of starch derivatives,β-cyclodextrin (β-CD)has received more and more attentions due to its excellent properties,such as rechargeable,biodegradable,low price,etc.In this work,a polymerizable mono-mer (β-CD-MAH)was obtained by using maleic anhydride (MAH)reacted with theβ-CD.Antimicrobial poly-merβ-CD-MAH-VBDMH was synthesized by the reaction betweenβ-CD-MAH and 3-(4′-vinylbenzyl)-5,5-dim-ethylhydantoin (VBDMH)using ammonium persulfate (APS)/sodium bisulfite (SBS)oxidation-reduction sys-tem as initiator,and characterized by solid-state 13 C NMR and FT-IR.The electrospun nanofibers were obtained by mixing solution of the synthesized antibacterial polymerβ-CD-MAH-VBDMH and cellulose acetate (CA). The optimum condition was determined by SEM.The chlorine content of the chlorinated nanofibers under the optimum condition was determined by iodometric titration,which indicated that the chlorinated nanofibers would have good antibacterial property.
