Abstract
A polyester material including a composite having a carbon nanostructure, which comprises carbon element, from 0.5 to 4 wt % of a first non-carbon non-oxygen element substance, and from 0 to 4 wt %, of a second non-carbon non-oxygen element. The first non-carbon non-oxygen element is selected from the group consisting of P, Si, Ca, Al and Na; the second non-carbon non-oxygen element is any one selected from the group consisting of Fe, Ni, Mn, K, Mg, Cr, S or Co, or a combination of at least two selected therefrom. The G peak and D peak of the carbon element in the Raman spectrum has a peak height ratio of 1-20 in the composite having a carbon nanostructure.
