TL;DR: In this paper, water vapor adsorption on montmorillonite (Mt), kaolinite (Kaol) and illite (Il) were performed to investigate the behaviors of water adaption on shale clay, and the effect of adsorbed water on pore structure characteristics, such as apparent pore size distribution (APSD), N2 BET specific surface area (N2-BET SSA) and pore volume (PV), were investigated.

Water Sorption and Distribution Characteristics in Clay and Shale: Effect of Surface Force
Jing Li,Xiangfang Li,Keliu Wu,Keliu Wu,Xiangzeng Wang,Juntai Shi,Liu Yang,Hong Zhang,Zheng Sun,Rui Wang,Dong Feng +10 more
TL;DR: In this paper, the thickness and stability of water film were investigated by vapor sorption experiments on clay and shale samples and an approach based on surface forces (disjoining pressure), which resulted in the instability of adsorbed film transition into condensed bulk liquid, was developed to describe molecule/pore wall interactions.
