Interfacial Polymer Rheology of Entangled Short-Chain Branched Ring Melts in Shear Flow

Tae Yong Ha,
Seung Heum Jeong,
Chunggi Baig

Abstract: We present a detailed analysis of the rheological behavior of entangled short-chain-branched (SCB) ring polymers at interfaces via direct comparison with the corresponding pure (unbranched) ring polymers using atomistic nonequilibrium molecular dynamics simulations of confined polyethylene melt systems under shear flow. To elucidate the general structural and dynamical characteristics of interfacial polymer chains, we analyze various physical properties of the chains in the bulk and interfacial regions separat… Show more
