•Novel flexible aerogels from MTMS and GPTMS were synthesized.•A maximum surface area of 410 m2 g-1 was obtained for F-40/30-2.•F-30/30-2 aerogel was highly flexible.•F-30/30-2 aerogel possessed a thermal conductivity of 0.0388 W m−1 K−1.•Young’s modulus of F-30/30-2 aerogel was found to be 0.46 MPa.
Flexible aerogels from methyltrimethoxysilane (MTMS) and 3-(2,3-epoxypropoxy)propyltrimethoxysilane (GPTMS) were prepared by employing a two-step acid–base sol–gel process along with the use of a surfactant. The alcogels have been aged for one day and two days. The resulting aerogels were flexible and possessed high surface areas. A maximum surface area of 410 m2 g-1 was obtained for F-40/30-2. The F-30/30-2 aerogel were highly flexible, possessed low thermal conductivity of 0.0388 W m−1 K−1 and a high Young’s modulus of 0.46 MPa.
