Poly(ε-caprolactone)/multiwalled carbon nanotube (PCL/MWCNT) composites with different MWCNT contents were successfully prepared by in situ bulk polymerization, which could make them good competitors for commodity materials such as general purpose plastics, while allowing them to completely retain their biodegradability. The mechanical properties of the PCL/MWCNT composites were effectively increased due to the incorporation of the MWCNTs. The composites were characterized using scanning electron microscopy, in order to obtain information on the dispersion of the MWCNTs in the polymeric matrix. In the case where 0.5 wt% of MWCNTs were dispersed in the matrix, the strength and modulus of the composite increased by 23% and 71%, respectively. In addition, the dispersion of the MWCNTs in the PCL matrix resulted in a substantial decrease in the electrical resistivity of the composites being observed as the MWCNTs loading was increased from 0 wt% to 0.5 wt%.
