A hybrid functional nanomaterial was synthesized by functionalizing carbon nanofibers (CNF) with polyhedral oligomeric silsesquioxane (POSS). The reaction between CNF and the amine group of ocataminophenyl POSS was achieved using carbodiimide chemistry. The CNF-POSS hybrids were designed to increase the reactivity of CNF without affecting its inherent properties. The reactive amine groups of CNF-POSS were further modified with an oligomer of polyimide polymer to improve the interaction with the polymer matrix, thus forming a nanocomposite with enhanced multifunctional properties. Functionalization was characterized using thermal gravimetric analysis (TGA), x-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM).
通过用多面体低聚倍半硅氧烷（POSS）对碳纳米纤维（CNF）进行功能化合成了一种混合功能纳米材料。使用碳二亚胺化学方法实现了CNF与八氨基苯基POSS的胺基之间的反应。设计CNF-POSS杂化物以提高CNF的反应性而不影响其固有性能。CNF-POSS的反应性胺基进一步用聚酰亚胺聚合物的低聚物进行修饰，以改善与聚合物基体的相互作用，从而形成具有增强多功能性能的纳米复合材料。使用热重分析（TGA）、X射线光电子能谱（XPS）和透射电子显微镜（TEM）对功能化进行了表征。
