Activation model for polymer and nanocomposite melts flow in fibrous bed

Kotomin S. V., Kulichikhin V. G.

Vol. 10, no spec

19-20

Flow of confined polymer melts in narrow channels is considered on base of the activation model for polymer melt friction. While melt infiltrates a dense fibrous bed under high pressure, the polymer segments in the adsorbed layer are gradually involved in flow and the effective activation energy increases as compared with that for the melt in bulk. The theoretical prediction was proved experimentally.
