A solution blending route to ethylene propylene diene terpolymer/layered double hydroxide nanocomposites

Abstract

Ethylene propylene diene terpolymer (EPDM)/MgAl layered double hydroxide (LDH) nanocomposites have been synthesized by solution intercalation using organically modified LDH (DS-LDH). The molecular level dispersion of LDH nanolayers has been verified by the disappearance of basal XRD peak of DS-LDH in the composites. The internal structures, of the nanocomposite with the dispersion nature of LDH particles in EPDM matrix have been studied by TEM and AFM. Thermogravimetric analysis (TGA) shows thermal stability of nanocomposites improved by %40°C when 10% weight loss was selected as point of comparison. The degradation for pure EPDM is faster above 380°C while in case of its nanocomposites, it is much slower.

Synthesis of partially exfoliated EPDM/LDH nanocomposites by solution intercalation: Structural characterization and properties

“…EPDM nanocomposites with different wt.% of DS-LDH were prepared by the solution intercalation method [20]. Firstly, the desired amount of DS-LDH was refluxed in 50 ml of toluene for 5 h at 85-90°C.…”

Novel Strategy for Producing Nanoplatelets to be Used as Building Blocks for Shaping Nanofibers through Layered Double Hydroxides and Poly Vinyl Alcohol

“…Compared with platelets of 3D LDHs, the nanoplatelets of LDHs have more advantages and can be collected to produce functional films or can act as building blocks of other multifunctional materials. When the particle sizes of LDHs decreased to the nanometer scale, they had more attractive applications in cellular drug delivery and polymer/LDH nanocomposites . Hitherto, there are many reports on LDHs.…”

Crystallization behaviors of hexagonal nanoplatelet MgAl–CO3 layered double hydroxide

“…Since the properties arising from quantum size effect strongly depend on particle size and shape [6,7], the control over size and shape thus becomes a desirable and important factor to their ultimate performance and industrial applications [8][9][10][11]. LDHs, when the particle size decreases to nanometer scale, are expected to lead to even more attractive applications in cellular drug delivery [12], polymer/LDH nanocomposites [13], thin films preparation, anti-ultraviolet reagent and so on. LDHs are conventionally synthesized by the co-precipitation route by adding metallic salts into alkaline solution [14].…”
