title: [Characteristics of absorption spectra of film doped with C60/C70 and asphalt].
abstract: This paper studied the characteristics of the UV-visible absorption spectra of alkyd varnish film, the characteristics of the IR absorption spectra and UV-visible absorption spectra of asphalt, and characteristics of UV-visible absorption spectra of film doped with C60/C70 and alkyd varnish, characteristics of UV-visible absorption spectra of C60/C70 and asphalt in the alkyd varnish. The experiments show that the alkyd varnish has bleaching effect on C60/C70, as spectral peak value of C60/C70 disappeared in the absorption curve, and the absorption curve shifted toward shorter wavelength, without affecting the absorption spectra of asphalt. Mingling C60/C70 and asphalt with alkyd varnish at the same time, the absorbance of the polymerization film decreased nonlinearly with the increase in wavelength in the range of 350-760 nm, and also the strength of the film was improved.
