“…Linearly growing films display some fuzzy structuration with small interpenetration of the alternating chains as has been demonstrated by means of small angle neutron scattering [39,40]. In these experiments, perdeuterated PSS chains, giving some scattering contrast with respect to hydrogenated chains, were deposited at regular levels during the film deposition.…”

“…Outra observação experimental interessante sobre o processo de formação dos filmes automontados é a possibilidade de ocorrer interpenetração 18,26,27 das cadeias dos polieletrólitos adsorvidos. Esse efeito foi primeiramente observado por Schmitt 26 , que investigou o ordenamento perpendicular das camadas, por espalhamento de nêutrons e difração de raios X. Neste estudo foi constatado não haver ordenamento de curto alcance, mas uma estrutura de super-redes podia ser detectada, indicada pelo ordenamento de longo alcance, entre quatro e seis camadas.…”

Neste estudo foi constatado não haver ordenamento de curto alcance, mas uma estrutura de super-redes podia ser detectada, indicada pelo ordenamento de longo alcance, entre quatro e seis camadas. Após a adsorção de uma camada de polieletrólito, a deposição da camada subseqüente se dá pela imersão do conjunto substrato-primeira camada na solução da segunda camada.…”

“…Such a strong interdigitation between adjacent polyelectrolyte layers was detected in neutron reflectometry measurements [5,7]. It was observed that polyanion layers may penetrate up to three consecutive polycation layers.…”

“…A consequence of this "intrinsic" charge compensation might be the Potential Profiles of PEM Measured by TIRM 3 strong interdigitation between adjacent layers found by neutron reflectometry [5][6][7]. The rms-roughness of the internal interfaces can be of the order of the thickness of a single layer.…”
