采用浓酸氧化法对碳纳米管进行表面改性,在 40 ℃超声波分散条件下,制备碳纳米管/环氧树脂复合涂料.通过对未加入碳纳米管、加入未经过浓酸氧化的碳纳米管、加入浓酸氧化的碳纳米管环氧树脂复合涂料进行耐酸碱盐试验.试验表明,加入未处理的碳纳米管的环氧树脂复合涂料防腐性能较纯净的环氧树脂涂料没有明显提高,加入浓酸氧化的碳纳米管环氧树脂防腐性能有了明显改善和提高.

Modifying the surface of multi-walled carbon nanotubes (MWCNTS) with concentrated sulfuric acid (H2SO4 / HNO3) oxidation. At 40℃ ultrasonic dispersion, prepare carbon nanotubes (MWCNTS) / epoxy resin composites. The anti-acid, anti-alkali and anti-salt tests of epoxy resin composite materials are carried out, first without MWCNTS, then with MWCNTS which are not oxidated with concentrated sulfuric acid, and then with MWCNTS which are oxidated with concentrated sulfuric acid. Experiments show that, the anticorrosive performance of epoxy resin composite materials with untreated carbon nanotubes are not obviously higher than the pure epoxy resin composite materials; the anticorrosive performance of epoxy resin composite materials with MWCNTS which are oxidated with concentrated sulfuric acid has been significantly improved and enhanced.
