摘要：

We investigate the physical properties of a purely kinetic k-essence model with polynomial type equation of state motivated in superconducting membranes. We compute the equation of state parameter w and discuss the physical evolution of a universe governed by the polynomial equation of state and, using the adiabatic speed of sound and energy density, we restrict the range of parameters of the model in order to have an acceptable physical behavior.
