ABSTRACT
Scanning probe microscopy (SPM) is a novel technique to investigate materials surfaces with high resolution. SPM can make the image of surface morphology and surface properties on the basis of the interaction between sharp cantilever tip and the sample surface. The application of SPM to the structure study of polymer crystals has produced new data on the aggregation structure of polymeric solids. Solid-state nuclear magnetic resonance (NMR) becomes a powerful technique to characterize thermal molecular motion. A new family of polyolefins synthesized by metallocene catalyst has been extensively developed. Copolymer is one of the most important target in polymer industry. Metallocene catalyzed have a narrow molecular weight distribution and a narrow comonomer distributions compared with Zieglar catalyzed one. Polymers having a large dipole moment and a polar conformation have a possibility to be ferroelectrics. Surface and interface of polymers play important roles in various industrial applications.
