Flexible and stretchable hybrid 3D graphene/Ti3C2Tx MXene composite thin film was fabricated using chemical vapor deposition (CVD) and selective etching method. The 3D graphene was grown via CVD approach at low pressure and methane as carbon source. While, the synthesis of Ti3C2Tx MXene was done using selective etching of Ti3AlC2 MAX phase. The 3D graphene and Ti3C2Tx MXene was sonicated and centrifuge with an organic solvent to form hybrid 3D graphene/ Ti3C2Tx MXene. As-product obtain in the form of clay-like then, it was encapsulated with the poly (dimethyl-siloxane) (PDMS) solution. The sample was baked to form composite thin film. The encapsulation of 3D graphene/Ti3C2Tx MXene with polymer matrix enables it to be used as flexible composite thin film. © 2018 Elsevier Ltd. All rights reserved.
