Through millions of years evolution and natural selection, various biological species own unique physiological structure amazing functionality. Biomimetic fabrication demonstrate remarkable trend development, artificial biomimetic materials intelligent functional surfaces have been extensively studied by scientists both theoretically experimentally. In general, traditional consisting metal, metal oxides, carbon some other polymer materials, which make outstanding contribution to the generation development engineering bionics science interface chemistry analysis. However, simpleminded are not capable deal with presence driving control micro nano device applications in science. It is well established that combination novel technology may lead promote progress smart integration multifunctional devices. More recently, a kind nanomaterials an atomic layer thickness named graphene has attracted most widely attention due its excellent properties, for instance ultrahigh carrier mobility, good electrical conductivity, high transmittance biocompatibility since it founded mechanical stripping adhesive tape, becomes new star scientific fields. Its stable physical/chemical properties applied electronic devices, optical biochips, even robots. Based on graphenes distinctive material micronano-structured special wettability be fabricated manner only contribute experimental research but also bring about revolution graphene-devices. A method surface multilevel-structures two-beam laser interference system proposed. Graphene oxide films different fabric bases reduced ablated Nd:YAG system. Periodic micronano-structures grating-like structures additional nanoscale produced during processing process appropriate power (0.4 W), resulted deoxidization abundant hydrophilic oxygen containing groups (OCGs) GO sheets. To original film, (RGO) exhibited more rough geometry, owned lower energy. Raman spectroscopy characteristiced, result D G band peaks RGO show neglectable changes contrast GO. The reason cutting ablation can defects edges sheets, leads increase peak. As result, spectra unobvious changes. Roughness (silk, cotton, nylon) further increased roughness surface. multi-structures formed double action base micronano-structure. bionic nylon substrate largest hydrophobic angle, ~156°. possesses superhydrophobic wettability, exhibits rainbow structural color existence periodic micronano-structures. We believe will important application prospects field bionics, major exploration breakthrough future optoelectronic wearable
