4、,星期一The separate preparation of alkyne-functionalized SWNTs and azideterminated polymers.Relatively mild coupling conditions,using CuI/DBU as the catalyst system.TGA of the PS-SWNT conjugates indicated a grafting density of 1 polymer chain for every 200-700 nanotube carbons,that consisted of approxi
5、mately 45%polymer.High solubility in organic solvents such as THF,CHCl3,and CH2Cl2.TEM and AFM showed the presence of polymer-coated SWNTs in solutions that remained stable for at least 3 weeks.Currently,we are extending this approach to the functionalization of SWNTs with other polymeric and functional materials.Conclusion第12页,共13页,编辑于2022年,星期一Thank you!第13页,共13页,编辑于2022年,星期一
