Abstract
Composite materials “aerogel—multi-walled carbon nanotubes” were prepared and characteristics of these materials were investigated. Multi-walled carbon nanotubes were embedded into silica and alginate aerogels at stage of sol. Effects of the multi-walled carbon nanotubes embedding on porosity, specific surface area and pore size distribution were analyzed. Multi-walled carbon nanotubes concentration ranged from 0 to 4.5 wt% for silica aerogel and from 0 to 30 wt% for alginate aerogel. It was observed that multi-walled carbon nanotubes occupy pores with diameter of 30–40 nm that correspond to the carbon nanotube diameter. BET analysis using nitrogen adsorption revealed the specific surface areas within 737–780 m2/g range for the composite “silica aerogel—multi-walled carbon nanotubes” and 317–459 m2/g range for the composite “alginate aerogel—multi-walled carbon nanotubes”.
