Surface Modification of ZrO2 by Silane and the Stability Study
Transparent inorganic-organic film with nanoparticle shows promising application in various technology field. In order to obtain transparent inorganic-organic composite film, the main challenge is to homogeneously disperse inorganic nanoparticle in polymer matrix without coagulation. This study demonstrated that silane-modification can obtain ZrO2 with chemically bonded silane. The ZrO2 nanoparticle shows good stability in various organic phase. Thus prepared inorganic-organic composite film has transparence as high as 80%.
Polarization reversal has been investigated in undoped and Ce3+-doped Sr0.5Ba0.5Nb2O6 in terms of a power-law random-field model. The random fields, excess polarization, and the volume contribution to the excess polarization were evaluated and found to be linearly dependent on the concentration of Ce doping. The origin of the random fields arising form Ce doping is discussed.
