“…Different elastic properties of the material components cause that the particles act as stress concentrators. Particle agglomeration promotes higher stress concentration, a more extensive cavitation and therefore a faster breaking [34]. Thus, the appearance of the maximum on the ε M = f(silica content) dependence is again in agreement with our other results.…”

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.

“…However, the strong tendency to agglomeration of nanofillers and the poor interfacial interaction between nanofillers and matrix largely restrict their wide applications, especially in industry [3][4][5]. The most effective and most commonly used technique to solve these problems is surface modification of inorganic nanofillers by using coupling agent [6,7]. This can be realized by simply grinding the modification agent and the nanofillers or adding the modification agent during the crushing process.…”

“…[20][21][22][23] Liu et al and Lei et al 24,25 reported the preparation of multiwalled carbon nanotube or nano-hydroxyapatite filled elastomeric nanocomposites with improved mechanical properties. However, there has been a dearth of research on the design and preparation of bioelastomers filled with nanosilica, although nanosilica is a kind of common and inexpensive filler [26][27][28] which has been approved for food, cosmetic as well as medical uses by the US FDA. 29 Herein, we describe the preparation and characterization of a novel bioelastomer nanocomposite, modified nanosilica/poly(glycerolsebacate-citrate) (mn-SiO 2 /PGSC), which has potential use in tissue engineering and drug delivery.…”

Modified nano-fumed silica (mn-silica)/ poly(glycerol-sebacate-citrate), in which mn-silica loadings varied from 0 to 20 phr, were prepared by in situ polymerization and surface modification. The influence of mn-silica loadings on the structure and properties of the composites was studied. Scanning electron microscope (SEM) and transmission electron microscope (TEM) photos showed that the mn-silica dispersed well as nano-scale network in the matrix, and exhibited good interfacial bonding with the matrix. The mn-silica filled composites exhibited excellent comprehensive properties relative to the unfilled elastomers. Specially, the tensile strength improved from 0.9 MPa to 5.3 MPa. Results of the in vitro degradation test suggested that mn-silica loading could adjust the degradation rate of the composites in simulated body fluid solution. The MTT colorimetry with L929 cells substantiated that the introduction of mn-silica weakened the cytotoxicity of elastomers and made the composites accepted as qualified biomedical materials.
