Polyhedral Oligomeric Silsesquioxane Encountering Tannic Acid : A Mild and Efficient Strategy for Interface Modification on Carbon Fiber Composites

Designing and controlling the interfacial chemistry and microstructure of the carbon fiber is an important step in the surface modification and preparation of high-performance composites. To address this issue, a tannic acid (TA)/polyhedral oligomeric silsesquioxane (POSS) hybrid microstructure, sim...

520 |a Designing and controlling the interfacial chemistry and microstructure of the carbon fiber is an important step in the surface modification and preparation of high-performance composites. To address this issue, a tannic acid (TA)/polyhedral oligomeric silsesquioxane (POSS) hybrid microstructure, similar to the topological structure, is designed on the fiber surface by one-pot synthesis under mild conditions. Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), and atomic force microscopy (AFM) show that the functionality and surface roughness of the fiber are significantly broadened. Correspondingly, the tensile strength (TS) of CF-TA/POSS100 and interlaminar shear strength (ILSS) of CF-TA/POSS100-based composites increased by 18 and 34%, respectively. Following that, a failure mechanism study is conducted to demonstrate the interphase structure containing TA/POSS, which is quite critical in optimizing the mechanical performance of the multiscale composites. Moreover, the strategy for the use of TA for constructing a robust coating to replace the traditional modification without affecting the fiber intrinsic strength is an improved design and provides a new idea for the development of high-performance composites
