介绍了同轴静电纺丝与传统热固化工艺相结合制备环氧树脂纳米纤维的方法。在流速为0.1和2mL h-1的条件下，芯液（20%w/v EP和6% w/v固化剂为乙醇/丙酮）和鞘液（10% PVP为乙醇）制备了直径为480 +/- 80nm的芯/鞘纳米纤维。将纳米纤维固化后，选择性去除鞘层PVP，得到平均直径为210 +/- 60nm的EP纳米纤维。ATR-FTIR分析表明，EP纳米纤维与芯液浇铸的EP膜没有明显差异。所提出的方法允许开发功能性EP纳米产品和制备热固化树脂纳米纤维。
A strategy is described to prepare epoxy resin nanofibers by combining coaxial electrospinning and traditional hot-curing processes. Core/sheath nanofibers with diameters of 480 +/- 80nm are prepared at flow rates of 0.1 and 2mL h-1 for the core (20%w/v EP and 6% w/v curing agent in ethanol/acetone) and sheath (10% PVP in ethanol) fluids. After the curing of the nanofibers and selective removal of the sheath PVP, EP nanofibers with an average diameter of 210 +/- 60nm are obtained. ATR-FTIR analysis shows that the EP nanofibers display no obvious difference compared with an EP film cast from the core solution. The method presented allows to develop functional EP nanoproducts and to prepare heat-cured resin nanofibers.
