Dispersion of SiO2 Nano particles on Epoxy Based Polymer Nano composites and Its Characterization

In present work we developed and characterized the thermosetting epoxy polymer nano composites containing different weight percentage (wt.%) of SiO2 nano particles ranging from 1 to 4 wt.% were prepared through solvent casting route. grain analysis, FTIR, shape recovery, impact stress, tensile, flexural strength and hardness were studied. The properties of composites were improved at 3 wt.% SiO2 nano particles, further loading of nano particles beyond 3 wt. % properties goes to suppressed which may depends on the dispersion of particles within matrix. Shape recovery test was done in this epoxy which may open the new gate for low cost shape memory polymer as we can say novelty of this experiment. The distribution and size of nano particles in epoxy based polymer matrix were examined through AFM analysis finally outlined.
