【摘要】：采用高速電火花線切割加工方法與電刷鍍工藝結(jié)合在鋁合金表面構(gòu)筑了類水稻葉多尺度層級結(jié)構(gòu)表面.利用掃描電子顯微鏡(SEM)、激光共聚焦顯微鏡(LSCM)、X射線衍射儀(XRD)和接觸角測量儀表征表面的形貌結(jié)構(gòu)、物相組成和潤濕特性.結(jié)果表明,電刷鍍獲得的雙尺度(微-納米)微觀結(jié)構(gòu)對表面疏水性起關(guān)鍵作用,而高速電火花線切割加工獲得的規(guī)則排列亞毫米級槽棱結(jié)構(gòu)進(jìn)一步放大了其平槽方向表面的疏水性能,使其未經(jīng)任何化學(xué)修飾即獲得優(yōu)異的超疏水特性,接觸角可以達(dá)到151°,且展現(xiàn)平槽和垂槽方向不同的疏水特性.這一研究將對各向異性功能材料結(jié)合超疏水材料的應(yīng)用起到一定的指導(dǎo)意義.
[Abstract]:The multi-scale hierarchical structure surface of rice leaves was constructed on the surface of aluminum alloy by high speed WEDM and brush plating.Scanning electron microscopy (SEM), laser confocal microscope (LSCM) and X-ray diffractometer (XRD) were used to measure the surface morphology, phase composition and wetting properties of the instrument.The results show that the microstructures obtained by brush plating play a key role in surface hydrophobicity.The regular arrangement of submillimeter grooves obtained by high speed WEDM further magnifies the hydrophobicity of the surface of the flat groove, making it obtain excellent superhydrophobic properties without any chemical modification.The contact angle can reach 151 擄, and the hydrophobic characteristics of flat groove and vertical groove are different.This study will play a guiding role in the application of anisotropic functional materials combined with super hydrophobic materials.
