Description

自捲曲薄膜及其製備方法和自捲曲方法
本發明涉及薄膜製備領域，尤其涉及一種自捲曲薄膜以及該自捲曲薄膜的製備方法和自捲曲方法。
聚合物材料由於具有較好的柔軟性，使其在人工血管、人工肌肉、智慧識別、回應、機器人以及感測器等領域都具有一定應用。然，諸如塑膠、橡膠等聚合物材料中，極少能夠在受到外界刺激後自動捲曲，而且捲曲過程和捲曲度不可控，使其大大限制了聚合物材料在這些領域更進一步的應用。
有鑑於此，有必要提供一種自捲曲薄膜的製備方法和自捲曲方法，能夠解決以上問題。
另，還有必要提供一種由上述製備方法制得的自捲曲薄膜。
本發明提供一種自捲曲薄膜的製備方法，包括：提供一靜電紡絲裝置，該靜電紡絲裝置包括一收集器；採用靜電紡絲方法在該收集器上製備一納米纖維基體薄膜，所述納米纖維基體薄膜由高分子納米纖維按第一排列方式排列而成，所述第一排列方式為該納米纖維基體薄膜的高分子納米纖維沿同一方向有序排列；採用靜電紡絲方法在該納米纖維基體薄膜遠離該收集器的表面製備一納米纖維可變形薄膜，從而得到一複合膜，該納米纖維可變形薄膜由高分子納米纖維按與該第一排列方式相同或不同的第二排列方式排列而成，該納米纖維可變形薄膜的高分子納米纖維包括一環境敏感型材料，使該納米纖維可變形薄膜在環境溫度升高或紫外光照射條件下收縮或膨脹；以及將該納米纖維複合膜從該收集器上分離並裁剪為所需尺寸，從而制得所述自捲曲薄膜。

通過靜電紡絲方法能夠精確控制所述納米纖維基體薄膜10以及所述納米纖維可變形薄膜21的高分子纖維排列方向，同時，通過控制該納米纖維基體薄膜10中的高分子納米纖維沿同一方向有序排列，可有利於控制該納米纖維可變形薄膜21的捲曲方向，而該納米纖維可變形薄膜21的所需捲曲程度（即該套管200的捲曲程度）可通過控制其自身的高分子納米纖維的排列方式而獲得。具體的，由於該納米纖維基體薄膜10中的高分子納米纖維沿同一方向有序排列，當該納米纖維可變形薄膜21在溫度升高或紫外光照條件下捲曲時，該納米纖維可變形薄膜21垂直於該納米纖維基體薄膜10中的高分子納米纖維的排列方向的側邊受到的阻力較大，而該納米纖維可變形薄膜21垂直於該納米纖維基體薄膜10中的高分子納米纖維的排列方向的側邊受到的阻力較小而發生捲曲。即，該納米纖維可變形薄膜21的捲曲方向與該納米纖維基體薄膜10中的高分子納米纖維的排列方向相互垂直。特別的，當該納米纖維可變形薄膜21的高分子納米纖維沿與該納米纖維基體薄膜10中的高分子納米纖維呈45度的另一方向有序排列時，該自捲曲薄膜100會捲曲為螺旋狀的套管200。
當該納米纖維基體薄膜10中的高分子納米纖維無序排列時，若該納米纖維可變形薄膜21在溫度升高或紫外光照條件下捲曲，該納米纖維可變形薄膜21無特定的捲曲方向。
