Investigation of PSt-MWCNT concentration on epoxyacrylate photopolymerization and conductivity of polymer films

► Polystyrene grafted multiwall carbon nanotube was synthesized by thiol-ene click chemistry via the thermal initiation method. ► Photopolymerization kinetics and conductivity changes were investigated by photo differential scanning calorimetry (photo-DSC) and four point conductivity measurements. ► 0.2% PSt-MWCNT loaded polymeric films had their electrical conductivity boosted by 6% more than non-additive polymeric films. ► Increase of the PSt-MWCNT loading negatively affects the light absorption behavior of the photoinitiator.
