Seed-assisted hydrothermal fabrication of nanostructured boehmite coating on carbon fiber

Novel approach to boehmite nanoparticles on the surface of carbon fiber (CF) fabrication has been developed. The AlOOH nanoplates were deposited using a seeded hydrothermal procedure at 160 °C for 5 h. As a result, a flower like coating was obtained with a predominantly perpendicular orientation to the CF surface. The structure analysis of the composite was performed by EDS, XRD, Raman, and ATR-IR methods. Surface roughness and interaction with ABS plastic were determined by SEM and contact angle equipment. It was shown that the contact angle decreased from 71.7 to 39.4o and the surface energy increased by 3.14 times through two-stage surface modification. Also, introduction of boehmite nanoparticles as a filler changed tensile strength by 1.5 times (from 12.17 MPa to 18.99 MPa) compared to the functionalized CF.
