= Polymers of intrinsic microporosity
{wiki=Polymers_of_intrinsic_microporosity}
Polymers of Intrinsic Microporosity (PIMs) are a class of materials that contain a highly porous structure on the microscopic scale, which arises from their unique molecular architecture. They are characterized by their rigid and contorted backbone structures, which prevent close packing of polymer chains, leading to the formation of micropores (defined as pores with diameters less than 2 nanometers) within the material.
