Abstract

The suspension poly(vinyl chloride) with the K number 70 (PVC S-70) compound was applied as a matrix of the nanocomposite, and the multi-wall carbon nanotubes (MWCNT) in the concentration range between 0.01 wt.% and 0.05 wt.% as a nanofiller. The T g determination was realized by means of DMTA, dielectric losses measurements and DSC measurements. In all cases the PVC matrix revealed lower T g comparing with corresponding composites with CNTs, and a clear relationship between the frequency, CNT contain and the T g was found. With an increase of the charging frequency an increase of T g of about 3 °C by DMTA measurements, realized by frequencies f = 1 Hz and f = 10 Hz, and of 9 °C by f = 1000 Hz, was noted. Independent on the frequency a maximum of the T g increase was observed by the CNT concentration of about 0.01–0.02 wt.%. Within investigated MWCNT concentration the lowest impact of MWCNT on the T g value were observed by the DSC measurements. This is probably due to quite different response of the nanotubes distribution on the temperature dependent PVC chain mobility.
