Nontronite and intercalated nontronite as effective and cheap absorbers of electromagnetic radiation.

The paper presents the thermal, structural and dielectric properties of natural nontronite and nontronite intercalated with DMSO, ethylene glycol and formamide. These materials were tested for the electromagnetic wave absorption ability. It was shown that nontronite and its intercalates were better absorbers than the materials previously obtained from kaolinite and halloysite.
