Gain deep insights into how fluids interact with your material’s surfaces. We provide specialized solutions to comprehensive characterize surface wettability, phase behavior, and wetting phenomena within confined pore spaces. Utilizing state-of-the-art vapor sorption analysis, we evaluate hydrophobicity/hydrophilicity trends and solid-fluid affinity. NMR relaxometry represents a cutting-edge method that offers immense potential for the rapid and non-destructive determination of wettability effects in confined pore spaces. These insights are essential for optimizing materials used in heterogeneous catalysis, separation processes, and energy storage systems where wetting behavior dictates performance.
We offer the following techniques for assessing the wetting behavior of confined liquids:
- High-resolution vapor adsorption experiments of water and organic liquids
- Determination of a wettability index (e.g., hydrophilicity index) by coupling adsorption experiments of adsorptives completely wetting the surface (e.g., Ar at 87 K) with adsorptives sensitive to the underlying surface chemistry (e.g., water)
- Intrusion of non-wetting liquids, e.g., water intrusion
- Novel technique based on NMR relaxometry for the fast quantification of wettability effects based on the relaxation time ratio of the adsorbed liquid film (T1,ads.film/T2,ads.film-ratio)
