碳纤维由于其良好的机械性能和在室温下的化学惰性，在医学应用中属于高度关注的材料。碳纳米纤维垫可以通过静电纺丝制备各种前体聚合物，然后进行热稳定和碳化，作为细胞生长的可能基质，特别是在组织工程中可能的3D细胞生长应用，正在研究中。然而，这种碳纳米纤维垫可能太脆，不能作为可靠的衬底。本文报道了一种以静电纺聚丙烯腈/ZnO纳米纤维垫为衬底制备高鲁棒性碳纳米纤维垫的简单方法。我们发现zno -共混聚丙烯腈（PAN）纳米纤维垫显著增加了纤维直径，从而增强了机械性能，从而支持组织工程应用。
Carbon fibers belong to the materials of high interest in medical application due to their good mechanical properties and because they are chemically inert at room temperature. Carbon nanofiber mats, which can be produced by electrospinning diverse precursor polymers, followed by thermal stabilization and carbonization, are under investigation as possible substrates for cell growth, especially for possible 3D cell growth applications in tissue engineering. However, such carbon nanofiber mats may be too brittle to serve as a reliable substrate. Here we report on a simple method of creating highly robust carbon nanofiber mats by using electrospun polyacrylonitrile/ZnO nanofiber mats as substrates. We show that the ZnO-blended polyacrylonitrile (PAN) nanofiber mats have significantly increased fiber diameters, resulting in enhanced mechanical properties and thus supporting tissue engineering applications.
