摘要：
The radical grafting of pentadecane onto MWCNTs has been investigated. A model for the functionalisation of MWCNTs with molten polyethylene is established, in which a pentadecane radical grafting reaction has been studied in order to determine the reaction conditions necessary to enhance the degree of grafting while minimising side reactions such as radical combination reactions. The effect of a nitroxyle-based radical scavenger (such as TEMPO) on the competition between the recombination of pentadecane radicals and addition to nanotubes has been explored. It was observed that the use of TEMPO resulted in a relatively higher grafting density without excessive pentadecane branching/cross-linking.
