Film formation and mechanical behavior of polymer latexes
- G.E.M.P.P.M., Villeurbanne (France); and others
The purpose of this lecture is to review the present state of the art in the field of film formation in relation with the mechanical behavior of polymer films. After a review of the theoretical approaches concerning film forming process, we show the influence of some experimental parameters (temperature, hygrometry {hor_ellipsis}) in the case of a core-shell latex obtained from polystyrene/Poly (Styrene co. butyl acrylate). Then, the mechanical behavior of polymer films is considered. The improvement of the mechanical strength of latex films during the last stage of film formation (i.e., gradual coalescence) is illustrated. Further analysis of the molecular process yielding mechanical behavior allows us to show how the comparison between prediction and experimental data can provide information on morphological changes, on the stability of this one, or on the formation of an interphase between constituting phases.
