Silica aerogels were synthesized by using tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) as co-precursors via the sol–gel method under the microwave irradiation condition. The optimal molar ratio of MTES:TEOS: EtOH: H₂O is 0.8:1:8:4, and the obtained aerogels showed the bulk density is 0.097 g/cm³, the surface area is 760.56 m²/g, and pore diameter is 6.06 nm, respectively. The microstructure on the skeleton of the bone networks was investigated by TEM, and the FTIR confirmed that the OH groups were substituted by the CH₃ groups prepared by MTES/TEOS co-precursor, the superhydrophobic property was described with a water contact angle up to 168.0°.

在微波辐射条件下，通过溶胶-凝胶法，以四乙氧基硅烷（TEOS）和甲基三乙氧基硅烷（MTES）作为共前体合成了二氧化硅气凝胶。MTES：TEOS：EtOH：H ₂ O的最佳摩尔比为0.8：1：8：4，所得气凝胶的堆积密度为0.097 g / cm ³，表面积为760.56 m ² / g，且孔隙直径分别为6.06nm。TEM观察了骨网络骨架的微观结构，FTIR证实OH基被MTES / TEOS共前体制备的CH ₃基所取代，超疏水性被描述为水接触角高达168.0°。
