“…Epoxies are found in a wide range of applications in different sectors including building, electronics, aircrafts, automobile and so on [1][2][3][4]. Cured epoxy resins often possess high performance properties, however due to their highly crosslinked structure they present high brittleness limiting their final application in many cases.…”

“…However, these nanofillers tend to form agglomerates that can become a critical site of failure which results in deterioration of the properties. Therefore, various investigation have been done in dispersing these nanofillers using different processing techniques to optimize the properties of such nanocomposites [13][14][15][16][17].…”

The present study investigated the influence of different compatibilizer on the dispersion of polyhedral oligomeric silsesquioxane (POSS). The effect of POSS dispersion in the epoxy resin in terms of mechanical, and thermal properties were reported. The three solvent used to disperse POSS in this work are ethanol, acetone, and toluene. The POSS was initially dispersed in the solvent followed by an addition in the epoxy resin by systematically varying the weight fraction from 0.5 to 8 wt%. Mechanical properties of nanocomposites were characterized in terms of elastic modulus, and fracture toughness. The obtained result illustrates that nanocomposites prepared by polar solvent dispersion such as ethanol showed an increase in values of elastic modulus and fracture toughness value. The increase in the modulus and fracture toughness value is due to the better interaction between POSS and ethanol disperse the POSS uniformly in the epoxy resin while avoiding the agglomeration. However, nanocomposites prepared by nonpolar solvent does not show substantial change in the mechanical properties. Fractured surface morphology was studied using scanning electron microscopy. Differential scanning calorimetry and dynamic mechanical analysis illustrates that with better POSS dispersion value of glass transition temperature (T g) increased. Fourier transformation infrared spectroscopy showed that POSS completely interacted with the epoxy resin and no phase separation was observed.

This experimental study investigates the effects of dispersion techniques on the mechanical properties of POSS‐epoxy nanocomposites. The POSS is dispersed into the epoxy resin by stoichiometrically varying the weight fraction from 0.5 to 10 wt% and materials are prepared using three different dispersion techniques. Various mechanical properties are reported as functions of processing parameters and weight fractions. It is found that the nanocomposites with highly dispersed POSS show higher modulus and toughness values. For example, nanocomposites prepared by ultrasonication show increases in elastic and flexural modulus values by average amounts of 23% and 15%, respectively. Also, it is found that fracture toughness values increased for all three processing techniques, with the highest increase by an average of 50% at 8 wt% of POSS inclusion for nanocomposites prepared by ultrasonication. TEM images of the nanocomposites demonstrate that the properties are also affected by the formation of soft domains at higher loading levels of POSS. Further evidence on the soft domains is found in the variations of Tg. FTIR spectroscopy shows evidence of SiOSi stretching, again suggesting the formation of compliant domains due to POSS‐POSS agglomeration. POLYM.
