To improve the dispersion of CFs in water, the surface of the CFs was modified by the ozone treatment.
The results revealed that HBPU-NH2 was uniformly coated and grafted onto the surface of the fibers (CFs-g-HBPU-NH2), thus its potential use as the sizing agent for CFs tows is promising.
The orientation and length (16.6 108.6 μm) of the MWCNTs were controlled by the surface treatment of the CFs and the growth time, respectively.
The functional groups on the surface of the plasma treated CF were studied through X-Ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared spectroscopy (FTIR).
The surface of the ozone-treated CFs contains hydrophilic functional groups such as C O, CO and O CO, which have been characterized by X-ray photoelectron spectroscopy.
Analysis of the distribution of surface proteins among the CF strains revealed a similar pattern.
Moreover, a thin high-textured (HT) pyrocarbon (PyC) layer (∼20 nm) was deposited on the surface of CFs during the growth of CNFs.
The CNTs were grafted onto the surface of CF through SiOSi bond formation due to the hydrolysis and self-condensation reactions of KH550.
We present a three-dimensional (3-D) hierarchical vertically aligned carbon nanotubes (VACNTs -CF hybrid by growing VACNTs -CFthybridface of CF fabyic.
