Exertion of Inhibiting Effect by Aluminosilicate Layers on Swelling of Solution Blended EVA/Clay Nanocomposite

Abstract: Summary: Ethylene vinyl acetate (EVA) copolymer/dodecyl ammonium ion intercalated montmorillonite (12Me‐MMT) nanocomposites were swelled in xylene under atmospheric condition. Swelling index of these nanocomposites decreased with filler loading indicating that the solvent uptake of these nanocomposites was inversely related to the filler contents. The volume fractions of nanocomposites showed an increasing trend with filler concentration because of unswelling effect exerted by aluminosilicate layers. The cross… Show more

“…The advantages of nanocomposites include enhanced mechanical properties, such as elastic modulus [1] and tensile strength [2,3], improved thermal properties such as coefficient of linear thermal expansion [4], heat distortion temperature [3], flammability resistance [5] and ablation performance [6], and other superiorities in oxygen barrier properties [7,8], water vapor transmission resistance [8] and solvent uptake [9]. Contrast to traditional composites, the physical property enhancements for nanocomposites are achieved with a rather small amount, usually less than 10 vol%, of addition of nanoscale particles.…”

“… where, n is the crosslink density; V r and V 0 are the volume fraction of nanocomposite in the swollen mass and molar volume of solvent respectively; χ is the polymer‐solvent interaction parameter. The volume fractions ( V r ) of the nanocomposite in the swollen mass are reverse of the swell ratio,33 i.e., V r = 1/ q . The value of χ could be obtained from the Flory Huggins's equation.…”
