Melt Compounding of Polymeric Nanocomposites

Abstract

Melt compounding of polymeric nanocomposites

Clay-containing polymeric nanocomposites and their properties

“…It is noteworthy that the effect of increased volume fraction does not affect the modulus. The reason is that adsorption reduces the mean value of the filler particle modulus and its aspect ratio, compensating for the increased volume [42].…”

The Role of Elongational Flow in Morphology Modification of Polyethylene/OMMt Nanocomposite System

“…the shear and elongational flow. The shear flow plays a significant role in polyethylene/OMMt manufacture processing but it is not able to change the system morphology, while, the elongational flow, involved in spinning and film-blowing processing operations, can induce considerably clay morphology variations [5][6][7][8][9][10][11][12][13]. In order to evaluate the effect of the elongational flow on the polyethylene/OMMt system morphology, the affinity between the matrix and the OMMt particles can be considered.…”

Synthetic, layered nanoparticles for polymeric nanocomposites (PNCs)

“…Similar explanation was recently offered for the behavior of PNC's based on PA-6 or PP. 101 Independently of the explanation, PNC with 2MHDI-modified clays, combined with high-energy sonication, resulted in better dispersion than that in the PNCs with di-methyl-benzyl-hexadecyl ammonium chloride (2MBHTA)-modified MMT. Judging by the values of n, there is no serious difference in behavior for PNC with MMT or FM, although the former clay showed higher yield stress than the latter.…”

“…The compounding line comprised SSE with the extensional flow mixer (EFM). 101 Figure 5 displays TEM micrographs of PNCs compounded using the same protocol, amount of clay, and magnification. It is noteworthy that Somasif MAE, Cloisite 1 15A, and Lucentite SAN, were pre-intercalated with 2M2HTA.…”
