Pillared interlayered clay (called PILC for short), a novel class of material, has become a heated topic in the fields of geology, chemistry and material science. This paper has summed up new achievements in this aspect, which include pillaring of vermiculites, phlogopites and synthetic clays, three kinds of PILC of Ga/Al, Si/Al and REE/Al, pillaring of acid_activated clay, surfactant modification, and properties of ion exchange and adsorption of PILC. Moreover, some potential applications of PILC are also briefly described.
