“…Our results for MEP-POSS are completely consistent with the results obtained by Dodiuk et al [48] who describes that an increased roughness is accompanied with a reduced T g and storage modulus. In this case, POSS nanocages act more like a plasticizer than as reinforcing agent.…”

“…From Fig. 8, it can be obviously perceived that incorporation of POSS nanoparticles to the PB chains due to formation of some POSS aggregates on the nanohybrid surface, as reported in the literature [39,40], significantly increase surface roughness. The roughness average value (R a ), calculated by SPM software, for the POSS containing and neat samples were 366 ± 14 and 618 ± 23 nm, respectively.…”

Hydroxyl functionalized nano-sized POSS or ethyleneglycol as diol monomers was incorporated to hydroxyl-terminated polybutadiene (HTPBD) chain in the presence of fumaryl chloride as extender. Blue light photocrosslinking system based on camphorquinone (photoinitiator) and dimethylaminoethyl methacrylate (accelerator) was applied to cure these two synthesized fumarate based macromers. Self-crosslinkability of unsaturated macromers and also crosslinking in presence of a reactive diluent were investigated in absence and presence of 1,4-butanediol dimethacrylate, respectively. Finally, photocured samples were characterized by XRD, SEM, equilibrium swelling study, TGA, DMTA, AFM and cell culture. The results showed that incorporation of POSS nanoparticle into the polymer matrix with a perfect distribution and dispersion can enhance thermal stability, mechanical and biocompatibility properties which can prove a good potential of this in-situ photocrosslinkable nanohybrid in medical applications.

“…It has been reported that monofunctional or multifunctional POSS can be incorporated into the backbone of epoxy resin to improve properties such as its thermal properties and reduce flammability properties. [25][26][27][28][29][30][31][32][33][34] The aim of this work was to develop a new kind of mercaptopropyl polyhedral oligomeric silsesquioxane (MPOSS)/diglycidyl ether of bisphenol A (DGEBA) nanocomposite. POSS containing mercaptopropyl (MPOSS) was synthesized and incorporated into DGEBA to form nanocomposites, in which MPOSS was distributed at the molecular level.…”

A novel polyhedral oligomeric silsesquioxane (POSS) containing a mercaptopropyl group [mercaptopropyl polyhedral oligomeric silsesquioxane (MPOSS)] was synthesized via the hydrolytic condensation of g-mercaptopropyl triethoxysilane in an ethanol solution catalyzed by concentrated hydrochloric acid and was used to modify epoxyamine networks by a cocuring reaction with diglycidyl ether of bisphenol A (DGEBA). The structure, morphology, and thermal and mechanical properties of these MPOSS/DGEBA epoxy nanocomposites were studied and investigated with thermogravimetric analysis/differential thermal analysis (TGA-DTA), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). From SEM analysis, we observed that the miscibility between epoxy and POSS occurred at a relatively high POSS content, which characterized this mixture as a polymer nanocomposite system. The impact test showed that MPOSS reinforced the epoxy effectively, and the SEM study of the impact fracture surface showed that the fibrous yielding phenomenon observed was an indication of the transition of the brittle stage to a ductile stage and correlated well with the large increases in the impact strength; this was in agreement with the in situ reinforcing and toughening mechanism. The TGA-DTA analysis indicated that the MPOSS/DGEBA epoxy hybrids exhibited lower thermostability at a lower temperature but higher thermostability and higher efficiency in char formation at an elevated temperature. Differential scanning calorimetry showed that the glass transition temperature (T g ) of the MPOSS/epoxy hybrids were lower than that of the neat epoxy.
