Abstrakt: The lamellar crystal orientation and crystal instable growth in polymer ultrathin films were studied. The orientation of lamellar crystal transforms from edge-on to flat-on with decreasing film thickness due to the enhancement of restriction effect of polymer-substrate on the edge-on lamellar crystals. Lamellar crystals in ultrathin films have a instable growth and become a dendrite at the growth front because of the diffusion-controlled growth.
