Modeling of the θ(lower critical solution temperature) in polymer solutions using molecular connectivity indices

In this paper the results of recent studies on the application of lower critical solution temperature (LCST) phenomena of polymer solutions to the surface modification of flat and spherical substrates are reported. It has been found that controlled polymer deposition can be achieved at temperatures exceeding LCST. The obtained polymer coating exhibits a peculiar surface morphology and, if particles are introduced, can be highly effective in pigment dispersions stabilizing. It has been established that the temperature induced polymer deposition can be carried out as the finely dispersed component precipitation on the substrate surface that goes along with the polymer deposition at temperatures exceeding LCST, which in its turn allows to modify the pigments surface when finely dispersed additives are incorporated into the surface modifying coating.

In this paper, the results of the recent studies on application of lower critical solution temperature (LCST) phenomena of polymer solutions to the surface modification of flat and spherical substrates are reported. It was found that a controlled polymer deposition can be achieved upon prevailing of the LCST, a peculiar surface topology of polymer coating and particles those remarkably effective in stabilizing pigment dispersiions. Second, the finding is that the temperature induces polymer deposition as the coprecipitation of a finely dispersed component on the substrate surface. That goes along with the polymer deposition after exceeding of the LCST which in turn allows for the tailored surface modification of pigments in that particulate additiives can be incorporated into the surface modifying coating.
