Abstract
Dielectric properties of biocompatible and biodegradable poly-ε-caprolone (PCL) and polylactide (PLA), as well as their nanocomposites, are measured in the millimeter (MM) wave band. It is found that the complex dielectric permittivity of PCL and its nanocomposites increases with temperature in the interval from 40 to 50â, while that of PLA and its nanocomposites increases in the interval from 85 to 90â. The samples of PLA with carbon nanotubes prepared with melamine show much lower absorption compared with the same samples prepared without melamine. The latter fact can be attributed to the formation of clusters of nanotubes in these samples.
