Through investigations, it is proved that the higher the concentration of nanoparticle suspension is, the higher the weight of embedding percentage (EPW) is. However, the increasing trend of EPW will minish quickly when the concentration exceeds 1%. In addition, the longer the process time of ultrasonic is, the higher EPW is. EPW is always higher when the distance between film and ultrasonic transducer is 1/2λ and 3/2λ, and lower when the distance is 1λ and 2λ. For 40nm ZnO particles, EPW of the film effected by ultrasonic with the frequency of 42kHz reaches the maximum.展开更多
