硬度低、耐磨性能差等固有缺点已成为限制聚合物材料在一些苛刻环境中工业应用的重要因素。为了改善表面硬度和耐磨性能，多种表面改性技术被用于聚合物材料的耐磨防护，其中在聚合物材料表面制备一层非晶碳薄膜被认为可有效提高材料表面硬度和耐磨性能。综述了聚合物材料表面耐磨性能提升用非晶碳基薄膜的研究进展，分析了非晶碳基薄膜在聚合物材料表面膜基结合强度不足的本质原因，聚合物材料与非晶碳薄膜两种材料在结构和性质上的不匹配使两者之间的突变界面在载荷作用下极易发生失稳，造成了膜基结合强度的不足。探讨和对比了目前常用于改善非晶碳基薄膜在聚合物材料表面膜基结合强度的改性技术。其中，利用等离子体对聚合物材料表面进行处理，可以诱导材料表面有机碳质结构向无机碳质结构的逐渐转变，使非晶碳薄膜在聚合物材料表面获得可靠结合强度。利用等离子体处理法可以在聚合物基体表面构建原位转变层，原位转变层通过化学键的形式，为非晶碳薄膜在基体表面获得了可靠的膜基结合强度，有效提高了聚合物材料表面的硬度和减摩耐磨性能。

Inherent shortcomings including low hardness and poor wear-resistance have become the important factors limiting the industrial application of polymer materials in some harsh environments. In order to improve the surface hardness and wear-resistance, various surface modification techniques have been applied to the wear protection of polymer materials. Among these surface modifications, fabricating a layer of amorphous carbon-based coating is one of the greatest potential approaches to improve the surface hardness and wear-resistance of polymer materials. The research progress of amorphous carbon-based coatings for improving the wear-resistance of polymer materials was reviewed, and the essential reason of poor adhesive strength of amorphous carbon-based coatings on the surface of polymer materials was analyzed. The mismatch between polymer materials and amorphous carbon coatings in structures and properties made the abrupt interface unstable under loading, resulting in the poor adhesive strength. Various methods commonly used to improve the adhesive strength of amorphous carbon coatings on polymer materials were discussed and compared. The reliable adhesive strength of amorphous carbon coatings could be obtained by the plasma treatment on the surface of polymer materials, which could induce a gradual transformation from organic carbonaceous structures into inorganic carbonaceous structures. An in-situ transition layer could be constructed on the polymer substrates by plasma treatment. The in-situ transition layer provided reliable adhesive strength between amorphous carbon coatings and polymer substrates via chemical bond, which endowed an effective improvement of the hardness, anti-friction and wear-resistance of polymer materials.
