"WebApr 10, 2024 · This means that the addition of MMT affects the helium adsorption region. The adsorption of gases is correlated with the solubility of the material, and an increase in the OMMT content leads to a decrease and then an increase in the solubility of the material. At 5% OMMT/PA6, the solubility is the lowest, and the gas adsorbable area is the lowest. " - Solubility of helium in water
