چکیده انگلیسی
In this work, we report on the effective implementation of the direct and scalable floating catalyst method to synthesize self-supporting carbon nanotube (CNT) aerogels at high deposition rates. Through the adaptable process conditions, the highly porous and ultralight CNT aerogels with densities ranging from 0.55 to 32 mg/cm3 are synthesized. The aerogels exhibit high porosity (>98%) and surface areas of up to 170 m2/g with tortuous pores easy accessible to molecules of interest. Their superior electrical conductivity (up to 106 S/m), in comparison with CNT aerogels produced through other methods, indicates high potential for energy applications. The thermal conductivity has been observed to be within the range of 0.127-0.137 W/m·K as a consequence of the ultralight structure. Polymer infiltration and subsequent curing do not disturb the three-dimensional percolating CNT network and constitute an accessible method for the production of various lightweight polymeric composites. The polydimethylsiloxane-based composites (4.5% wt) with electrical conductivity enhanced by â¼16 orders of magnitude and thermal conductivity double that of pure matrix are particularly promising for use in bio-integrated devices and flexible composites.
