“…The reduction in thermal stability at a low temperature may be due to the existence of the organic surface modifier on clay which exhibits lower thermal stability. In addition, the ammonium salt that attached to the clay may act as a catalyzer towards the degradation of the polymer matrix through the Hoffman degradation mechanism; a similar observation has been reported by several researches [33,[41][42][43]. The TIDT of the epoxy nanocomposites decreases as the concentration of the OMMT increases.…”

In this work, the optimum filler loading to prepare epoxy/organoclay nanocomposites by the in-situ polymerization method was studied. Bi-functionalized montmorillonite at different filler loading (0.5, 1.0, 2.0, 4.0 wt %) was dispersed in epoxy resin by using a high shear speed homogenizer. The effect on morphology, thermal, dynamic mechanical, and tensile properties of the epoxy/organoclay nanocomposites were studied in this work. Wide-angle X-ray scattering (WAXS) and field emission scanning electron microscope (FESEM) studies revealed that possible intercalated structures were obtained in epoxy/organoclay nanocomposites. Thermogravimetric analysis (TGA) shows that epoxy/organoclay nanocomposites exhibit higher thermal stability at the maximum and final decomposition temperature, as well as higher char content, compared to pristine epoxy. The dynamic mechanical analysis (DMA) indicate that storage modulus (E′), loss modulus (E″), cross-link density and glass transition temperature (Tg) of the nanocomposites were improved with organoclay loading up to 1 wt %. Beyond this loading limit, the deterioration of properties was observed. A similar trend was also observed on tensile strength and modulus. We concluded from this study that organoclay loading up to 1 wt % is suitable for further study to fabricate hybrid nanocomposites for various applications.

“…It should be pointed out that the T g of M‐50 composite is only 70.8°C. This is mainly attributed to the plasticizing effect of DOP, which decreases the molecular interactions and therefore results in a decreasing T g and decreasing HDT that will be mentioned later.…”

Low‐cost mineral fillers, including mica, calcium carbonate (CaCO3), and alumina oxide (Al2O3) were used to modify poly(vinyl chloride) (PVC)/α‐methylstyrene–acrylonitrile copolymer (α‐MSAN)/chlorinated polyethylene (CPE) blend. With the addition of mineral fillers, the thermal conductivity, flexural modulus and overall thermal stability were improved; however, loss in tensile properties, impact and flexural strength, and initial thermal stability accompanied the other improved properties. The theoretical modeling results indicate that mica has a more effective potential to increase the thermal conductivity and better interfacial interaction with the polymeric matrix. Therefore, mica is the best candidate for enhancing the properties of the composites. POLYM. COMPOS., 39:553–559, 2018. © 2016 Society of Plastics Engineers

The modern trend is to prepare hybrid material using nano clay. Formation of nano clay, an exfoliated clay, and proper dispersion in a polymer matrix remains a challenge. The green composite so formed by clay polymer mixing has many improved properties such as high Tg (glass transition temperature), high flame resistance, high tensile strength, and improved barrier properties, which may find application in textile industry, automobile industry, environmental and polymer engineering field.
