通过静电纺丝技术制备纯淀粉纳米纤维膜,并在密闭容器中和戊二醛蒸汽进行交联。利用环境扫描电子显微镜(ESEM)、傅里叶变换红外光谱(FT-IR)对纤维交联前后的表面形貌和结构进行观察和分析,通过电子万能材料拉伸试验机、接触角测试仪等考察了交联反应对纤维膜性能的影响。结果表明,戊二醛与淀粉分子之间发生了缩醛化交联反应,淀粉纳米纤维膜经戊二醛蒸汽交联后仍能较好的保留原纤维的形态,并且拉伸性能和耐水性能均得到一定程度的提高。
通過靜電紡絲技術製備純澱粉納米纖維膜,併在密閉容器中和戊二醛蒸汽進行交聯。利用環境掃描電子顯微鏡(ESEM)、傅裏葉變換紅外光譜(FT-IR)對纖維交聯前後的錶麵形貌和結構進行觀察和分析,通過電子萬能材料拉伸試驗機、接觸角測試儀等攷察瞭交聯反應對纖維膜性能的影響。結果錶明,戊二醛與澱粉分子之間髮生瞭縮醛化交聯反應,澱粉納米纖維膜經戊二醛蒸汽交聯後仍能較好的保留原纖維的形態,併且拉伸性能和耐水性能均得到一定程度的提高。

The starch nanofiber mats were prepared by electrospinning,and crosslinked by deal with glutaralde-hyde vapor in a sealed containers.The morphology and structure of the fibers (before and after crosslinking) were characterized by SEM and FT-IR,and the properties of the product were measured by tensile test and con-tact angle measurements.Test results show that,acetalization reaction occurred between the intermolecular of glutaraldehyde and starch,the morphology of crosslinked fibers can be grossly preserved compared with the un-crosslinked starch fibers,and tensile properties and water resistance of the fiber mats have been greatly im-proved after glutaraldehyde crosslinking.
