Measurement of Thermochromic Material Spectral Transmittance Spectra

A brief introduction of thermochromic materials was made,the principles and methods of measuring the transmittance were described,the test platform was built,the transmittance was measured,and the data was analyzed.The results show that the transmittance of material will change when wavelength changes,the transmittance of the material will increase firstly and then decrease with the increase of wavelength,the transmittance of the material will decrease firstly and then increase with the increases of temperature.
