The oriented nanostructures from block copolymers have great interests because of their numerous potential applications in optoelectronics, sensors, nanogenerator, and electronic circuits. The microdomains of block copolymers could be aligned by applying the external fields such as shear, electric force to overcome interfacial interactions. In this study, highly oriented SiCN mesostructured films have been successfully fabricated by using self-assembled poly(vinyl)silazane-block-polystyrene (PVSZ-b-PS) diblock copolymer with no electric filed, and followed by annealing up to 900oC under Ar atmosphere. Their nanostructured films were characterized by atomic force microscopy (AFM), field emission scanning electro microscopy (HR-SEM) and X-ray diffraction (XRD). These exciting results have a great potential to open a new field for the generation of mesostructured non-oxide ceramic or metal–ceramic materials for a broad class of applications. |
