SANS Studies on the Formation of PANI Nanoparticles in the Reverse Micelles

摘要

The formation of polyaniline (PANI) in the reverse micelles of poly(oxyethylene) nonylphenyl ether,(NP5,H(CH_2)_9Ph(OC_2H_4)_5OH),was investigated by small-angle neutron scattering (SANS).The reverse micellar solution containing initiators in the inner part of reverse micelle was prepared with surfactant (NP5),water,cyclohexane and an initiator (ammonium persulfate (APS)).The core-shell sphere model containing smearing effect reveals that the polymerization occurs on the shell layer of the reverse micelles.Shell thickness averages varied from 48 A to 109 A with increases of monomer concentration.
