Crystallization of Thin Polymer Films on Amorphous Foreign Surface

1 Crystallization of Thin Polymer Films on Amorphous Foreign Surface 

FTIK measurement was used to identify the formation of hydrogen bond. For the C=0 groups of PHB, there are several bands related to its different states. The weak intramolecular hydrogen bonds between the C=0 and C-H in the CH3 side

The effect of strong interfacial interaction on the crystallization behavior of polymers can be well illustrated by the melt recrystallization behavior of oriented polymer thin 

The aforementioned recrystallization behavior of polymer thin films with controlled crystal structure and orientation may be of great significance. Through this process, micropatterned polymer thin films with well-defined crystal stmcture and orientation can be simply prepared by selective carbon coating with the help of a mask and subsequent melt recrystallization of the preoriented polymer films [78]. The patterned polymer thin films exhibit exceptional anisotropic optical properties and may potentially find applications in the fields of nanometer- and/or micrometer-sized stractures for optoelectronics and optical applications [80,81].
