摘要:
分别以载玻片、陶瓷片、镀铝聚酯膜、普通白纸和Cu片为基底,聚四氟乙烯(PTFE)粉末为原料,采用电子束蒸发法沉积聚合物薄膜。对于基底载玻片和陶瓷片,采用2%H2SO4溶液刻蚀预处理后在其上沉积厚度为125 nm的聚合物薄膜; Cu片用不同浓度草酸刻蚀预处理后在其上沉积厚度为62 nm的聚合物薄膜; 而基底镀铝聚酯膜和白纸,直接在其上沉积不同厚度的PTFE薄膜。通过傅里叶变换红外光谱仪(FT-IR)、原子力显微镜(AFM)、接触角测量仪分别对薄膜的成分、表面形貌和疏水性进行表征。结果表明:经刻蚀处理后,基底表面粗糙度皆增大。载玻片由亲水性转变为疏水性,陶瓷片无明显变化,Cu片显示良好的疏水性; 沉积薄膜后,载玻片表面接触角增大到138°,而陶瓷片接触角可以达到142°; 在粗糙度较大的白纸表面沉积不同厚度的PTFE薄膜,膜厚对接触角具有显著影响,当膜厚为225 nm时,接触角达到151°,滞后角为8°; 经0.5%草酸刻蚀的Cu片表面膜的接触角达到153°,滚动角为2°,具有良好的超疏水性。
Abstract:
The glass slide, ceramic, polyethylene terephtalate film coated by aluminium, white-paper and copper sheet were used as substrates, polytetrafluoroethylene(PTFE)power as raw material, polymer films were deposited by a electron beam evaporation method. Glass slides and ceramic supports were etched by 2% H2SO4, and then deposited on polymer film with the thickness of 125 nm, and the copper etched by H2C2O4 solution with different concentrations then deposited of 62 nm. The polyethylene terephtalate film coated by aluminium and the paper were deposited with PTFE film of different thicknesses directly. The components of coatings,surface morphology and hydrophobicity were characterized by Fourier transform infrared spectroscopy(FT-IR), atomic force microscopy(AFM)and contact angle(CA)measurement. Results showed that the roughness of both substrates increased and the wettability of glass slide turned to hydrophobicity from hydrophilcity after etching, but no significant changes were observed in ceramic, copper sheet showed good hydrophobicity; after deposition, CA on glass slide and ceramic substrate increased to 138° and 142°, respectively. The different thicknesses of PTFE films were coated on white-paper of higher roughness, CA was significant influenced by the different thicknesses, and in the thickness of 225 nm, CA of film reached 151°, hysteresis angle was 8°. CA was 153° and hysteresis angle was 2° on copper etched by 0.5% H2C2O4, thus it had showed better hydrophobicity.
