Within the field of materials science and engineering, anisotropic materials outstand for their great versatility. Their properties are different depending on the direction in which they are produced, being able to adapt better to heterogeneous behaviors, typical in almost all applications (i.e. tissue engineering or architecture), without having to pursue a compromise in the properties of the material. In this work, a comparative study was carried out involving electrospun PCL/gelatin scaffolds obtained with different alignments. A mechanical and morphological characterization was conducted in the parallel and perpendicular directions with respect to the fiber formation with the aim of analyzing the anisotropy of the samples. The random system presented an imperfect homogeneous nanostructure, which made the scaffold to be isotropic, whereas the aligned system allowed the appearance of discontinuities, giving rise to fracture points (grains) and thus inducing the breakdown of the sample.

通过静电纺丝获得的 PCL/明胶支架的各向异性特性

在材料科学和工程领域，各向异性材料以其强大的多功能性而著称。它们的特性取决于它们的生产方向，能够更好地适应异质行为，这在几乎所有应用（即组织工程或建筑）中都是典型的，而不必追求材料特性的妥协。在这项工作中，进行了一项比较研究，涉及以不同比对获得的电纺 PCL/明胶支架。为了分析样品的各向异性，在纤维形成的平行和垂直方向上进行机械和形态表征。随机系统呈现出不完美的均匀纳米结构，这使得支架是各向同性的，
