“…Ours previous papers [8,13,14] analyzed kinetics more deeply (in the considered cases a maximum on the dependence of the polymerization rate on the silica content was observed). On the other hand, mechanical properties of this type of composites were often investigated (e.g.…”

A comprehensive study of model systems based on poly(ethylene glycol) dimethacrylate and two methacryloxymodified silicas (Aerosil R7200 and R711) were investigated to find possible correlation between the stability of the monomer/silica dispersion, curing kinetics, composite morphology and physical and mechanical properties of the final hybrid material. The monomer/silica dispersions were cured photochemically. The investigated parameters: Zeta potential, polymerization rate and conversion, glass transition, surface roughness and mechanical properties were found to be synchronous; when plotted as function of silica content, they showed maxima or changes in the trend at the same filler loading. This threshold (optimum) silica content in the composition was about 5 wt.-% for the investigated systems. The results obtained are discussed in terms of the solvation cell (which influences dispersion stability) and the interphase layer formation as well as their changes below and above of the threshold filler content.

“…Although there are many reports on the effect of silica addition on various properties of monomer/silica formulation and the resulting composite, there are no reports on the stability of the formulation understood as its susceptibility to flocculation (this issue was only briefly mentioned in our previous works [13,14]). …”

“…The mechanical and physical properties of ionic liquids alone are greatly improved by the incorporation into a solid matrix, forming an ionogel. Generally, the solid fraction of ionogels in the case of silica matrix can be low (2-3%) and of the order of 10% in the case of polymer matrices [159]. This low content of solid in ionogels not only changes the physical appearance of ionic liquid from fluid into gel-like, but also provides many other advantageous properties such as mechanical robustness, dimension stability, and improved thermal stability.…”

“…32 Applications of ionogels include electrolytic membranes (with solid electrolytes), catalytic membranes, drug delivery systems and others. 33,34 Most often the radical polymerization of (meth) acrylates in ILs gives increased polymerization rates and higher molecular weights and yields that that in conventional organic solvents or in bulk. Acceleration of the polymerization is associated with the increased propagation rate coefficients and reduced termination rate coefficients.…”
