Abstract
|
Polymercarbon nanotube (CNT) composites are promising structural materials due to high formability, good<br />mechanical properties and high electrical conductivity. The main targets of polymerCNT composite research<br />are to reach a homogeneous distribution of the CNT in the polymer, and to achieve a high adhesion between<br />CNT and polymer. The resulting properties were less frequently investigated till now, for example<br />nanoindentational hardness and Youngs modulus have not been studied to our knowledge. Nanoindentation was<br />chosen as method of investigation, because it requires a small piece of sample material and it is nearly damage<br />free. Beside an MWNT free reference samples with 2, 4, and 6 wt% of multiwalled carbon nanotubes (MWCNT)<br />were produced using the master batch dilution method starting from a composite with 15 wt% MWCNT.<br />Nanoindentation investigations showed an increase in hardness and Youngs modulus of the samples by<br />increasing the MWCNT concentration. This increase was about twice the weight fraction of MWCNT in the<br />nanocomposite samples.
