摘      要：The ability to control surface wettability and liquid spreading on textured surfaces is of interest for extensive *** materials have prominent advantages for producing the smart coatings with multiple functions for strain ***,we report a simple method to prepare flexible hydrophobic smart coatings using graphene-polymer *** of individual patterns in the films were created by laser engraving and controlled the contact angle of small drops by pinning the contact lines in a horizontal tensile range of 0-200%.By means of experiments and model,we demonstrate that the ductility of drops is relied on the height-to-spacing ratio of the individual pattern and the intrinsic contact ***,the change of drop size was utilized to measure the applied strain and liquid viscosity,enabling a strain sensitivity as high as 1068μm2/%.The proposed laser-etched stretchable graphene-polymer composite has potential applications in DNA microarrays,biological assays,soft robots,and so on.
