A low temperature method for the fabrication of architected ceramic composites contining graphene is developed based on the infiltration of lightweight graphene oxide (GO) micro-lattices with a preceramic polymer. Self-supported highly porous three-dimensional (3D) GO structures fabricated by direct ink writing are infiltrated with a liquid organic-polysilazane (a compound of Si, C, H, N), and subsequently pyrolyzed at temperatures of 800–1000 ºC to activate the ceramic conversion. These ceramic composites replicate the patterned GO skeleton and, whereas the graphene network provides the conductive path for the composite (electrical conductivity in the range 0.2–4 S cm⁻¹), the ceramic wrapping serves as a protective barrier against atmosphere, temperature (up to 900 °C in air) and even direct flame. These structured composites also show hydrophobicity (wetting angle above 120°) and better load bearing capacity than the corresponding 3D GO lattice. The process is very versatile, being applicable to different liquid precursors.

基于轻质氧化石墨烯（GO）微晶格与预陶瓷聚合物的渗透，开发了一种用于制造连续石墨烯的建筑陶瓷复合材料的低温方法。通过直接墨水书写制造的自支撑的高度多孔的三维（3D）GO结构被液体有机聚硅氮烷（Si，C，H，N的化合物）浸润，然后在800-1000ºC的温度下热解为激活陶瓷转换。这些陶瓷复合材料复制了图案化的GO骨架，而石墨烯网络为复合材料提供了导电路径（电导率范围为0.2–4 S cm ^-1），陶瓷包裹层可作为保护层，防止大气，温度（在空气中高达900°C）甚至直接火焰。与相应的3D GO晶格相比，这些结构化复合材料还具有疏水性（润湿角大于120°）和更好的承载能力。该方法非常通用，适用于不同的液体前体。
