THE MORPHOLOGY INVESTIGATION OF HAMMER-LIKE C60 CONJUGATED POLYSTYRENE IN SOLUTION
【Abstract】 A hammer like C 60 conjugated polystyrene was synthesized via atom transfer radical polymerization using bromine ended polystyrene as an initiator.The self assembly aggregating behavior of the hammer like polymer was investigated by DLS,GPC and TEM.Two narrow distributions with hydrodynamic radius 29 5 nm and 1 3 nm were observed in DLS,attributed respectively to the aggregates and single hammer like polymer molecules.In the eluograph of GPC,two distributions were also observed,attributed respectively to the aggregates and single hammer like polymer.In TEM,micelle particles with average diameter 65 nm were observed,agreed well with the results obtained by DLS.The diameter of aggregates of two hammer like C 60 conjugated polystyrene samples was compared and possible explanations were proposed.
