研究了熔融混合对多壁碳纳米管（MWNTs）与聚苯乙烯（PS）基体相互作用的影响。发现原始MWNTs与溶液中PS之间存在相互作用，但不足以使MWNTs溶于溶剂。相比之下，熔融混合显著增强了MWNT与PS之间的相互作用，这导致PS功能化MWNT的数量增加，在某些溶剂中表现出良好的溶解性。熔体混合对这种增强相互作用的机理归因于熔体混合过程中的化学键和物理相互作用。
The effect of melt mixing on the interaction between multi-walled carbon nanotubes (MWNTs) and polystyrene (PS) matrix has been investigated. The interaction between pristine MWNTs and PS in solution was found to exist but not strong enough to allow MWNTs to be soluble in solvent. In contrast, this interaction between MWNTs and PS was significantly enhanced by melt mixing, which led to increased amount of PS-functionalized MWNT exhibiting good solubility in some solvents. The mechanism of melt mixing on this enhanced interaction was attributed to both chemical bonding and physical interaction during the melt mixing.
