Title : Carbon nanotubes and carbon nanotubes-polymer compositions for photovoltaics and aviation application
Abstract:
The properties and application of various carbon nanomaterials such as fullerenes, carbon nanotubes, and graphene are strongly dependent on their atomic structures and interactions with other materials. In our work we are wide investigated all of the carbon nanomaterials for dual use. Fullerenes were wide investigated by us in polymer solar cells based on various conjugated polymers such as poly(3-hexylthiophene) (P3HT), polyazomethines (PAZ) or poly({4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl}{3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (PTB7). Moreover, in the past years we extensive analyzed how do graphene and graphene oxide obtained by chemical vapor deposition and modified Hummers method changed electrical and mechanical properties of constructed devices such as polymer solar cells, polymer fuel cells or thermoelectrochromic sensor.
Recently, carbon nanotubes (CNTs) hold the most promise among nanoscale materials. Nanotubes can exist both as a single-walled nanotubes (SWCNTs) and as a multiwall nanotubes (MWCNTs). Depending on the chirality along the graphene sheet, either semiconducting or metallic electronic states are created.
The first goal of this work is shown that CNTs can be applied as electrode or hole transporting layer in organic solar cells. The second goal is created polymer compositions based on CNTs and various polymers such as (sensitive information) towards aircraft application as light (0.5 g/cm3) and mechanically and thermally stable. Specific attention is devoted to analyzed amount and type of carbon nanotubes (SWCNTs and MWCNTs) together with smart technology to create films for selected electrical and mechanical properties of constructed devices.
