THE INFRARED ABSORPTION SPECTRUM OF ZINC OXIDE WHISKERS WITH TETRAPOD SHAPE WAS RECORDED AND COMPARED WITH ZNO POWDER. THE ABSORPTIONS OF MICROWAVE AND SOUND WERE INVESTIGATED WITH A RESULT SHOWING THAT THE ZNO WHISKERS ARE OF EXCELLENCE AS ABSORBENTS OF MICROWAVE AND SOUNDPROOFING. THE RESULTS OF VIBRATION DAMPING TESTS OF POLYVINYL CHLORIDE INDICATE THAT THE MATERIAL CONTAINING THE TETRAPOD SHAPED ZNO WHISKERS APPEARS SUPERIOR DAMPING CHARACTERISTICS.“,”The infrared absorption spectrum of zinc oxide whiskers with tetrapod shape was recorded and compared with ZnO powder. The absorptions of microwave and sound were investigated with a result showing that the ZnO whiskers are of excellence as absorbents of microwave and soundproofing. The results of vibration damping tests of polyvinyl chloride indicate that the material containing the tetrapod shaped ZnO whiskers appears superior damping characteristics.
