| dc.description.abstract | Ce travail présente une nouvelle méthodologie pour analiser la densité de charge superficielle à température ambiante avec une grande resolution. La microscopie à force électrostatique (EFM) a eté utilisée pour mesurer la densité de charge supeficielle des cheveux vierges, décolorés et traités avec un polymer cationique. La technique de microscopie à force atomique (AFM) a eté utilisée simultanément pour évaluer les changements de morphologie, de rugosité et d’épaisseur des cuticules. Les images EFM nous ont permis de visualiser la dègradation et la distribution du polymère sur la superficie des cheveux. Grâce à la puissance analytique de l'image EFM, les différents degrés d'altération des fibres capilaires avec le polymère ont pu être observés. Les images de la densité de charge superficielle et de la distribution du polymère sur la surface des cheveux ont été présentées à la lumière de l'EFM | pt_BR |
| dc.description.resumo | A new method for high-resolution analyses of hair surface charge density under ambient conditions is presented in this paper. Electrostatic force microscopy (EFM) is used here to analyze changes in surface charge density in virgin hair, bleached hair, and hair treated with a cationic polymer. The atomic force microscopy technique is used concomitantly to analyze morphological changes in hair roughness and thickness. The EFM images depict exactly how the polymer is distributed on the surface of the hair fiber. The EFM’s powerful analytical tools enabled us to evaluate the varying degrees of interaction between the hair fiber surface charge density and the cationic polymer. The surface charge density and the polymer’s distribution in the hair fibers are presented in the light of EFM measurements | pt_BR |
