“…Thus, for PPy mass loadings lower than 5% (see Table ), only patchy, submonolayer deposition is expected, rather than a uniform PPy shell. This grain size problem apparently was not recognized by Huijs and co-workers, who claim that uniform overlayers of PPy are obtained even at overlayer thicknesses of only 1 nm . The final column in Table refers to the colloid stability of the coated latex, as judged by visual inspection.…”

“…These composite materials are being marketed under the “ConQuest” tradename and have potential applications as anti-static and anti-corrosion coatings. In an effort to understand the behavior of these film-forming latexes both our group and also Huijs and co-workers prepared poly( n -butyl methacrylate) (PBMA) particles as a model colloidal substrate. PBMA latex has a minimum film-forming temperature that is around ambient temperature, i.e., somewhat higher than conventional film-forming latexes but much lower than high T g materials such as PS or poly(methyl methacrylate) (PMMA) latex.…”

Polypyrrole (PPy) has been deposited from aqueous solution onto two types of near-monodisperse poly(alkyl methacrylate) latexes and the resulting composite particles have been extensively characterized using SEM, DCP, XPS, FTIR, and electrical conductivity measurements. Poly(methyl methacrylate) (PMMA) latex is more difficult to coat than the polystyrene latexes previously reported by our group in that the deposited PPy overlayer is much less uniform. This difference is most likely related to the greater hydrophilicity of the PMMA surface. The poly(n-butyl methacrylate) (PBMA) latex has intermediate hydrophobic character, and, as a result, PPy overlayers on this substrate are somewhat more uniform than those obtained for PMMA particles. The PPy-coated PBMA latex is an interesting model system for understanding the behavior of PPy-coated film-forming latexes such as DSM's ConQuest (PPy-coated polyurethane particles). The lightly cross-linked outer shell of PPy hinders film formation significantly but conductive films can be obtained in the presence of coalescence aids such as N-methyl pyrrolidone. This cosolvent acts as a plasticizer for the PBMA latex and allows a reasonable degree of film formation at ambient temperature.

“…Latex particles having a poly(butyl methacrylate) (PBMA) core of about 700 nm and a very thin polypyrrole (PPy) shell were reported by Huijs & Lang 2000. Further studies illustrated the effect of the thickness of the polypyrrole shell on latex properties (Huijs et al, 2001).…”

under the supervision of Professor William R. Fawcett. So far, he advised 19 master and 12 doctoral theses, and published more than 100 scientific papers. He was a National Secretary of the Ibero-American Society of Electrochemistry from 2000 to 2002 and a Director of the Electrochemistry and Electroanalytical Chemistry Division of the Brazilian Chemical Society from 2006 to 2010. Professor Motheo's recent research interests are the application of electrochemical, photo-electrochemical and sonoelectrochemical methods for the degradation of endocrine disruptors, the development of materials combined with conduction polymers for corrosion protection of iron and aluminum alloys, and the study of adsorption at electrode/solution interfaces in the absence of faradaic processes.
