Structural and electrical properties of PVDF-CNT composite
Misiurev, Denis ; Dallaev, Rashid (oponent) ; Sobola, Dinara (vedoucí práce)
Electrospininig has been proven one of the most popular and widely spreaded method of producing high quility of vibers with required parametrs. The quality and morfology of produced vibers is based on many parametrs such as humidity, doses of material, applied voltage etc. Limitations of ceramic piezomaterials (brittleness, toxicity of lead-containing samples, difficulties of complicated shapes preparations, etc.) forced the research in the field of piezoelectric polymers. One of them is polyvinylidene fluoride (PVDF). It could be prepared in various forms: thin films, bulk samples, fibers. PVDF fibers attract the most attention because of high flexibility, lightweight, mechanical stability, chemical inertness. Properties of PVDF fibers can be tuned using dopant material: ceramic particles, metal nanoparticles, graphite materials as graphene oxide or carbon nanotubes (CNT).
