Build a Rigid-Flexible Graphene/Silicone Interface by Embedding SiO₂ for Adhesive Application.

ABSTRACT: An effective strategy was developed to enhance the adaptability of graphene/silicone matrices under external stimuli by embedding nanoscale SiO₂ into the graphene/silicone interfaces as a buffer layer. Chemically reduced graphene (rGE) was first covered by SiO₂ using an in situ preparation, forming sandwichlike rGE/SiO₂ (rGES). Then, rGES was integrated into methyl vinyl polysiloxane, followed by vulcanization, producing the final rGES/silicone rubber (SR) nanocomposite. Such interfacial modification actually built a rigid-flexible SiO₂ buffer layer between rGE and polysiloxane. Obvious improvements were seen in both thermal and mechanical properties due to improved interfacial interaction. In a vulcanized rGES/SR system, the addition of 30 wt %
