“…However, pure SR has poor tensile strength and tear strength, which limits its practical application. To overcome this drawback, researchers have tried to incorporate various inorganic fillers such as nano-SiO 2 [2], carbon nanotube [3], nano-Al 2 O 3 [4], clay [5] and so on into polymer matrix so as to improve the mechanical properties by combining the advantageous performance of the polymer matrix with that of the inorganic fillers. Various nanoparticles as the fillers and/or reinforcing agents are of special significance in this respect, since they possess unique physical and chemical properties which contribute to effective reinforcement of polymer matrices [6,7].…”

Nanoclay (NC) reinforced high‐density polyethylene (HDPE) composites were prepared by different melt compounding methods using (1) a single screw extruder (SSE), (2) twin screw extruder (TSE), (3) a combination of SSE and extensional flow mixer (EFM), and (4) a bowl mixer masterbatch method (MB). PE‐grafted maleic anhydride (PE‐g‐MA) was used as a compatibilizer. EFM increased complex melt viscosity (η*) of the HDPE/NC composites as compared to the neat HDPE and also provided a better interaction between HDPE and NC to create slightly lower melt η* as compared to MB and PE‐g‐MA composites. The low viscosity melt behavior of the pure HDPE changes to more solid like melt behavior in the PE‐g‐MA HDPE/NC composites in the low frequency (ω) region. PE‐g‐MA + EFM method exhibited better impact strength compared to the other HDPE/NC composites. Using the PE‐g‐MA and masterbatch compounding methods had a beneficial role in improving mechanical properties. POLYM. ENG. SCI., 57:324–334, 2017. © 2016 Society of Plastics Engineers

“…The improvement of the elongation at break may be attributed to the following three reasons: (1) the delocalised and absorbed stress due to the uniform dispersion of silicate layers in RTV matrix; (2) the enhanced slipping of the clay tactoids due to the 'external hook' effect of the dendrimer; (3) the plasticising effect of the dendrimer in RTV matrix. [26] The toughening mechanism of FR-DOMt in RTV was illustrated in Scheme 2. As to the nanocomposites with different amounts of Mt, they showed another trend.…”

The aim of our research was to study the effect of flame-retardant dendrimer modified organic montmorillonite (FR-DOMt) with different ratios on the structure and properties of room-temperaturevulcanised silicone rubber (RTV). The physical and mechanical properties of RTV nanocomposites were improved with the addition of FR-DOMt additives. The RTV nanocomposites exhibited better thermal stability. T onset of RTV/FR-DOMt-3 was 310 C, 100 C higher than that of pure RTV. RTV/FR-DOMt-3 nanocomposite possessed the highest elongation at break, 500%. This was 46% higher than that of pure RTV. In addition, these RTV nanocomposites showed an increased FR behavior. By adding 3À15 phr of FR-DOMt into pure RTV matrix, a linear decrease of burning rate together with an increase of LOI values were obtained. SEM and TEM observations of RTV/FR-DOMt-3 demonstrated that the exfoliated silicate layers dispersed uniformly in this nanocomposite.
