Study on the Crystallization Kinetics of Polymer Thin Films

The crystallization kinetics of polymer thin film has a great difference from that in the bulk. Generally, the growth rate of the crystal confined in thin film reduces with decreasing film thickness, which is believed that the interaction between chains and substrate is responsible for the decrease of the growth rate. In addition, the ratio of film thickness over crystal thickness is also a key parameter in determining the growth rate. The relationship between the crystal lateral size and the crystallization time also dominates the crystal growth mechanism in polymer thin film.
