碳纳米管(CNT)增强铜复合材料的实验结果表明，铜/碳纳米管复合材料的综合拉伸强度与碳纳米管直径呈抛物线关系，即碳纳米管直径越小，铜/碳纳米管复合材料的综合强度越大。铜/碳纳米管复合材料强度的大幅度提高归因于电化学沉积后碳纳米管在电解液和复合材料中的良好分散，以及电化学沉积过程中形成的良好的界面结合。碳纳米管直径越小，总界面结合面积越大，因此复合材料的合成强度越大。
Experimental results of carbon nanotube (CNT) reinforced copper composites (Cu/CNT) have shown that the resultant tensile strength of Cu/CNT composite is CNT diameter dependent, in a form of parabolic relationship that the smaller the CNT diameters the greater the resultant strength of the Cu/CNT composites. The largely increased strength of Cu/CNT composited is attributed to the good CNT dispersion in both the electrolyte and in composite after electrochemical deposition, as well as to the good interfacial bonding formed by the electrochemical deposition process. Smaller CNT diameters result in greater total interfacial bonding area thus the greater resultant strength of the composite.
