Competitive Adsorption between a Polymer and Solvents onto Silica
Abstract
International audience ; In polymer nanocomposites, particle-polymer interactions play a key role both in the processing and in the final properties of the obtained materials. Specifically, for silica, due to the surface polarity, surface modification is commonly used to improve the compatibility with apolar polymer matrices, in order to prevent agglomeration. In this work, a new way to investigating the polymer-silica affinity and determining dispersibility parameters (HDP) of silica particles in the 3D Hansen space using a solvent approach is proposed. These parameters are estimated from the assessment of the stability of suspensions in a set of organic solvents. Based on the respective locations of the solvent, polymer and silica representative points in the 3D Hansen space, the adsorption of a given polymer in solution in a given solvent can be predicted. This is shown with the industrial precipitated silica Zeosil ® 1165MP in combination with polystyrene and polybutadiene. It is shown that silanization of the silica particles 1 decreases the adsorption of polystyrene, even though due to this surface treatment silica comes closer to polystyrene in the Hansen space. This counter-intuitive effect is rationalized based on the consideration of an adsorption parameter χ S computed from the relative locations of the solvent, polymer and particles in the 3D Hansen space. Basically, this parameter is related to the respective distances of the solvent and polymer representative points to that of the particle in Hansen space.
