Search of new, better materials for conductive paste for thick film compositions deposited by screen printing was the main aim of this work as well as influence investigations of carbon nanotubes addition to functional phase of thick film paste. Different types of carbon nanotubes such as single-walled nanotubes (SWCNT), multi-walled nanotubes (MWCNT) and non purified non segregated nanotube clusters were mixed with conductive silver pastes. Obtained mixtures were screen-printed and fired or cured. The measurements of resistivity were carried out and changes in resistivity of obtained CNT/silver thick films in comparison to common silver layer were shown. The influence of different conditions of firing process were also investigated especially to avoid high temperature degradation and oxidation of carbon nanotubes. Obtained mixtures with optimal conductivity will be used for further experiments.
