| titleOfInvention | Calculation method of pore parameters of transparent porous material |
| abstract | By simply measuring the transmittance of a transparent porous body, approximate values of pore parameters such as average pore radius, pore diameter distribution, pore number density, and specific surface area can be easily obtained in a short time. A method for calculating a pore parameter of a transparent porous body according to the present invention includes inputting a parallel plate thickness and a porosity of a transparent porous body processed into a parallel plate shape, and performing a wavelength sweep from the near ultraviolet region to the visible region. The transmittance spectrum of the transparent porous body measured in this way is input to a computer, and the value obtained by dividing the logarithm of the transmittance spectrum by the parallel plate thickness of the transparent porous body is set to the light source wavelength of the spectrophotometer. Is plotted against the inverse fourth power or the inverse square of the value divided by the refractive index, and linear multiple regression analysis is performed to calculate the slope parameter, strain parameter, and vertical axis intercept, and the air and porous body interface from the vertical axis intercept And the effective refractive index of the transparent porous body is calculated from the reflectance at the porous body interface, and the pore diameter distribution of the transparent porous body is calculated from the inclination parameter and the strain parameter.
