“…This increase in T g can be attributed to the restricted mobility of the epoxy chains caused by the strong interactions between the NPs and the epoxy matrix. 51,52 The addition of 2 wt% of Fe 2 O 3 and ZnO, however, slightly decreased the value of the glass transition temperature by imparting some plasticizing effect.…”

Epoxy-based nanocomposite coatings were formulated by incorporating various types of inorganic nanoparticles (NPs) (ZrO 2 , ZnO, Fe 2 O 3 , and SiO 2 ). The effect of the incorporation of various NPs on the mechanical, thermal, and morphological properties of these epoxy coatings has been studied. A facile direct incorporation technique has been utilized for the dispersion of the NPs in the epoxy matrix via highspeed mechanical stirring and ultra-sonication using acetone as a solvent. The incorporation of these NPs augmented the mechanical and thermal properties of the epoxy coatings. The results revealed that the incorporation of small amount of these NPs improved the mechanical properties of the coating in all cases, with the SiO 2 -reinforced sample being relatively better in both mechanical and thermal properties. The incorporation of Fe 2 O 3 and ZnO resulted in a decrease in the thermal stability and glass transition temperature (T g ) of the coatings, while incorporation of SiO 2 and ZrO 2 increased the thermal stability as well as T g of the coatings. A notable increase of 71% in hardness together with 26% increase in the elastic modulus of the epoxy coating was observed with the incorporation of 2 wt% SiO 2 NPs.

“…Nanoindentation has been established as a reliable tool for measuring mechanical properties of polymer composite at the submicron scale [1][2][3][4][5][6]. An extensive study of nanoindentation on poly (methyl methacrylate) (PMMA) composites has been reported by Jee and Lee [6,7].…”

The present work aims to compare the scratch hardness (H s ) with the indentation hardness (H IT ) obtained from nanoindentation measurements of exfoliated graphite/poly (methyl methacrylate) (EG/PMMA) composites. EG/PMMA composites with thickness 50 μm each were produced by in situ melt mixing method. Scratch hardness was measured from the scratch width formed at low applied load during the course of the scratch measurements. The measured scratch hardness values were compared with the indentation hardness. There is a good correlation between the scratch hardness and the indentation hardness at low indentation depths, with a linear relationship between hardness and the reinforcement content of exfoliated graphite.

“…Как извест-но, создание эффективных полимерных композитов на основе термопластов возможно с использованием раз-личных методов, из которых наиболее перспективным является экструзионный метод введения наполнителя в объем полимера через его расплав. Одним из основных достоинств этого метода по сравнению с растворной тех-нологией и полимеризацией in situ является отсутствие многостадийности процесса и растворителей [22][23][24].…”
