Wetting phenomena of carbon by some molten alloys and molten polymers were investigated. Wettability of carbon by molten Cu was controlled adding alloy metal to Cu. When Si is added much enough to form SiC interface layer; the wettability of carbon becomes better and the contact angle between carbon and molten Cu-Si alloy is about 40°. It is also observed that the molten Cu-Si alloy infiltrated into a porous carbon.Wetting of vertically aligned CNTs that look like thin film on substrate was investigated. CNTs were vertically grown on a quarts substrate by thermal CVD technique. CNTs showed good wettability with polyethylene glycol and polyacetal, and poor wettability with water. When the CNTs adhere to the substrate strongly using Ti, Si, and Fe as catalysts, CNTs remain on the substrate after the wetting test CNT/ polyacetal composite were obtained after the solidification and it showed well aligned CNTs inside.

研究了熔融合金和熔融聚合物对碳的润湿现象。在Cu中加入合金金属，控制了Cu熔体对碳的侵蚀。当Si的加入量足以形成SiC界面层时，C的润湿性变好，C与Cu-Si合金熔体的接触角约为40°。研究了Cu-Si合金熔体对多孔碳的浸润作用，并对垂直排列的碳纳米管在多孔碳上的润湿行为进行了研究。采用热CVD法在石英衬底上垂直生长了碳纳米管。碳纳米管表现出良好的润湿性与聚乙二醇和聚缩醛，和差的润湿性与水。当使用Ti、Si和Fe作为催化剂时，CNT牢固地粘附在基底上，在润湿测试后CNT保留在基底上，固化后获得CNT/聚缩醛复合材料，并且其显示出内部良好的定向CNT。
