Gallium-based liquid metals (GLMs) exist as atypical liquid-phase at and near room temperature while being electrically thermally conductive, enabling copious applications in soft electronics thermal management systems. Yet, solid are affected by interfacing with GLMs, resulting metal embrittlement device failure. To avert this issue, mechanically durable tunable diffusion barriers for long-term reliable metal-solid based on the deposition of various diamond coatings designed synthesized, they feature high chemical inertness extraordinary mechanical resistance. The show superlyophobicity (GLM contact angle ≥ 155°) nonstick toward thereby achieving mobility GLM droplets (sliding 8-12°). excellent barrier anti-adhesion performance proven experiments (3 weeks) coated titanium alloy (Ti) samples GLMs. electrical conductive coating deposited Ti is stable over a period 50 h. As proof-of-concept switch demonstrated, signifying that films potent means to achieve integration
