Impact of C-CVD synthesis conditions on the hydraulic and electronic properties of SiC/CNTs nanocomposite microfiltration membranes

In this study, commercial SiC ceramic microfiltration membranes were coated with carbon nanotubes (CNTs) using chemical vapor deposition (CVD) to obtain a conductive and hydrophobic membrane material. order have better control of the surface electronic properties developed material, two adjacent fractional factorial designs (25-2) implemented quantify CNTs synthesis parameters influence. The design experiments revealed that quantity synthesized was mainly controlled by CVD temperature, duration iron catalyst concentration. structure layer temperature within investigated parameter range (650–850 °C). It demonstrated pure water permeability anti-correlated yield due an increase in membranes' hydrophobicity potential pore blockage. largest amount obtained at 850 °C for least 1 h showed relatively low electrical resistance good microwave absorption. Finally, such tunable nanocomposite material has further improve filtration performances widespread application.
