  • Abstract : Although the presence of slippage at polymer-polymer interfaces has been widely reported in experiments and MD simulations, its effect on the stability of superposed fluid layers undergoing shear has not been adequately addressed. Therefore, we formulate a mathematical model and under the assumption of one layer being asymptotically thin we derive a novel weakly non-linear evolution equation for the interface to study the linear stability and system dynamics. A slip-induced Turing-type instability is found.
