Presentation Title:
A Convenient Preparation Method for Polymer/Carbon Nanotube Composites with A Core/Shell
Structure by In Situ Polymerization Induced by UV Irradiation
Abstract:
Since the first report on the preparation of polymer/carbon nanotube(CNT) nanocomposites
[1], recently the incorporation of CNTs into polymer matrices has been believed to deliver
enhanced functionality and unique properties to the host material [2]. Significant attention has
been focused on design and fabrication of CNT/polymer nanocomposites with superior
properties, such as high mechanical strength, processability, flexibility, and electric conductivity
[3].
Herein we report a convenient preparation method for polymer/multi-wall carbon nanotube
(MWNT) composites in the absence of acids from in situ polymerization induced by UV
irradiation. The polymer with functionalized side chain can be synthesized by exposing the amine
monomer to sunlight. In a similar manner, the polymer/MWNT composites were obtained by
simply mixing the amine monomer and MWNTs followed by exposure to natural sunlight. Figure
1 shows the ball structure of prepared polymer. In the obtained polymer/MWNTs, MWNT was
trapped by polymer in a core/shell structure, which is shown in Figure 2. Polymer/MWNT
composites with different ratios of MWNT were investigated.
