Electrospinning is a widely used technology for obtaining nanofibers from synthetic and natural polymers. In this study, electrospun mats from collagen (C), polyethylene terephthalate (PET) and a blend of the two (C-PET) were prepared and stabilized through a cross-linking process. The aim of this research was to prepare and characterize the nanofiber structure by Fourier-transform infrared with attenuated total reflectance spectroscopy (FTIR-ATR) in close correlation with dynamic vapor sorption (DVS). The studies indicated that C-PET nanofibrous mats shows improved mechanical properties compared to collagen samples. A correlation between morphological, structural and cytotoxic proprieties of the studied samples were emphasized and the results suggest that the prepared nanofiber mats could be a promising candidate for tissue-engineering applications, especially dermal applications.
静电纺丝是一种广泛应用的技术,用于从合成聚合物和天然聚合物中获取纳米纤维。在本研究中,制备了由胶原蛋白(C)、聚对苯二甲酸乙二酯(PET)以及二者混合物(C-PET)制成的静电纺丝垫,并通过交联过程使其稳定化。本研究的目的是通过傅里叶变换红外衰减全反射光谱法(FTIR-ATR)并结合动态蒸汽吸附(DVS)来制备和表征纳米纤维结构。研究表明,与胶原蛋白样品相比,C-PET纳米纤维垫的机械性能有所改善。强调了所研究样品的形态、结构和细胞毒性特性之间的相关性,结果表明所制备的纳米纤维垫可能是组织工程应用,特别是皮肤应用的有前途的候选材料。
