Impedimetry and microscopy of electrosynthetic poly(propylene thiophenoimine)-co-poly(3,4 ethylene dioxythiophene) dendritic star copolymer

Olowu, Rasaq A; Williams, Avril; Ndangili, Peter M.; Ngece, Rachel F; Mailu, Stephen N; Baker, Priscilla; Iwuoha, Emmanuel (2011)

The electrochemical impedance spectroscopy of generation 2 poly(propylene thiophenoimine)-co-poly(3,4 ethylene dioxythiophene) dendritic star copolymer (G2PPT-co-PEDOT) film was studied in LiClO4 solution. The results show ...
Modulation of the interfacial electrochemistry of surfactant-functionalised polypyrrole chemical sensor systems

Iftikhar, Faiza J.; Baker, Priscilla G. L.; Baleg, Abdul M.; Ndangili, Peter M.; Mailu, Stephen N.; Iwuoha, Emmanuel I (Pergamon, 2011)

The redox properties of electro-polymerized polypyrrole (Ppy) doped with different surfactants were studied in acid medium. It was found out that the addition of different surfactants affect the redox properties as evidenced ...
Synthesis and characterization of poly (propylene imine) dendrimer–Polypyrrole conducting star copolymer

Baleg, Abd Almonam A; Jahed, Nazeem M; Arotiba, Omotayo A; Mailu, Stephen N; Hendricks, Nicolette R; Baker, Priscilla G; Iwuoha, Emmanuel I (Elsevier, 2010)

A star copolymer based on poly(propylene imine) (PPI) dendrimer core (generations 1–4) and polypyrrole (PPy) shell was prepared. The synthesis procedure involved a condensation reaction between PPI surface primary amine ...
