Abstract:

This study is concerned with the preparation and properties of a new class of bionanocomposites from renewable resources. Epoxidized linseed oil (ELO) and 3-glycidylpropylheptaisobutyl-T8-polyhedral oligomeric silsesquioxane (G-POSS) (2, 5, and 10 wt %) were cross-linked, and Fourier transform infrared spectroscopy (FTIR), dynamic mechanical thermal analysis (DMTA), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) were employed to characterize the POSS-reinforced oil-based polymer networks. No POSS aggregates were observed for the 2 wt % G-POSS nanocomposite by SEM. POSS-rich particles with diameters of several nanometers were observed in the nanocomposites with 5 and 10 wt % G-POSS. Enhanced glass transition temperatures and storage moduli of the networks in the glassy state and rubber plateau were observed to be higher than those of the POSS-free oil based polymer network, due to the reinforcement effect of POSS cages.
