Optical Properties of Polytetrafluoroethylene–Carbon Nanotube Composite in the Light Spectrum Range 320–1000 nm
The influence of carbon nanotube (CNT) concentration (in wt.%) on optical properties of polytetrafluoroethylene (PTFE) was investigated by the spectrophotometric analysis. The effect of transparency increasing at 4–25 times was detected in the spectrum range λ = 320–1000 nm during the addition of CNT to PTFE. It was shown that the increasing CNT concentration and the thickness of the sample lead to decreasing of the composite’s transparency in the ultraviolet (UV) band and also to increasing of transparency in infrared (IR) band.
