(i) While the backside of the sample is purged with a gas, the sample is immersed into a liquid wetting agent. (ii) The gas pressure is gradually decreased, and the gas flowrate is monitored; or, the gas flowrate is gradually decreased, and the gas pressure is monitored. (iii) When the gas flow stops, the remaining pressure in the system corresponds to the largest pore-mouth size. (iv) The pore-mouth size distribution can be calculated through a “dry curve” and a “wet curve”, which are curves of the gas flowrate vs. pressure at the dry and wetted states of the sample. The calculation of the pore-mouth size and the pore-mouth size distribution is the same as that based on the conventional bubble point method. The measurement of the pore-mouth size of the porous materials is of great importance when they are used as the substrates for surface coatings."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of determining surface pore mouth diameter distribution of porous material","description":"The invention relates to a method for the determination of the pore-mouth size distribution at the surface of porous materials.
