一种可多材料自动实时混合电纺直写装置
本专利技术涉及静电纺丝,尤其是涉及一种可多材料自动实时混合电纺直写装置。
技术介绍
静电纺丝是前驱体在强电场中喷射拉伸成纤工艺,即电场作用下,喷头处液滴由球形变为圆锥形(即“泰勒锥”),进而圆锥末端拉伸出射流并演化成微纳米级纤维细丝。该方法制造装置简单、纺丝成本低廉、可纺物质种类繁多、工艺可控,已成为有效制备纳米纤维的主要途径之一。静电纺丝技术已经制备了种类丰富的纳米纤维,包括有机、有机/无机复合和无机纳米纤维。然而,利用静电纺丝技术制备纳米纤维还面临一些需要解决的问题(HuangZM,ZhangYZ,KotakiM,etal.Areviewonpolymernanofibersbyelectrospinningandtheirapplicationsinnanocomposites.Compositesscienceandtechnology,2003,63(15):2223-2253.)。电纺直写技术通过缩小喷头至收集板距离、降低纺丝工作电压,利用纺丝射流的稳定阶段直写沉积有序纳米纤维,克服传统静电纺丝射流螺旋鞭动和纤维无序沉积缺陷,具有设备简易、工艺简单、材料兼容性好等优点。电纺直写将加速静电纺丝技术在微纳制造领域的推广应用,是柔性电子产业最具潜力的制造技术之一(ZhouFL,GongRH,PoratI.Massproductionofnanofibreassembliesbyelectrostaticspinning.PolymerInternational,2009,58(4):331-342.)。在现实需求 ...
