Experimental Materials.Pyromelliticdianhydride (PMDA) and 4, 4`-oxydianilline (ODA) (Supplied by Aldrich Chemical Co.) were used for the synthesis of poly (amide acid) (PAA), PMDA and ODA were purified by vacuum sublimation and recrystallized. 1-Methyl-2-pyrrolidinone (NMP) was used as the solvent.
These results are because clay layers acts as insulating material and represents thermal barrier effect.

The scattering phenomena of the elastic waves is a wave phenomena when the elastic waves transmit in the medium which have not continuous interfaces or heterogeneous bodies, their direct effects result in the magnification of the local displacements or local stress concentration or earthquake, they have various harms, one of these is the breakage and the rupture of the engineering materials.
