Growth of large-scale patterned, wrinkle-free graphene and the gentle transfer technique without further damage are most important requirements for practical use graphene. Here we report growth wrinkle-free, strictly uniform monolayer films by chemical vapor deposition on a platinum (Pt) substrate with texture-controlled giant grains thermal-assisted patterned onto arbitrary substrates. The designed Pt surfaces limited numbers grain boundaries improved surface perfectness as well small thermal expansion coefficient difference to provide venue characteristic. allows complete substrates any ripples, tears, or folds. transferred shows high crystalline quality an average carrier mobility ∼5500 cm2 V–1 s–1 at room temperature. Furthermore, this tolerance variations in types morphologies underlying
