A series of Polyimide (PI)-Organically modified clay nanocomposites were made to enhance tensile modulus, thermal stability of rigid PI. PI was made from 3', 4, 4'.-biphenyltetracarboxylic dianhydride (BPDA), p-phenylediamine (PDA). Montmorillonite, one type of layered clay, was treated by n hexadecyltrimethylammonium bromide salt. XRD indicated that OMMT… (More)
