| 摘 要： | 研究了利用超声波将40nm的ZnO微粒子嵌入到多孔纺织材料中的可行性和影响因素。研究表明，纳米分散液浓度越高，膜片的增重百分率W（％）也越高，浓度增加到1％时，增重率的增长幅度明显减缓；超声波作用时间越长，增重百分率W（％）也越高；膜片在在距离超声波换能器λ／2和3λ／2处具有较高增重百分率W（％），而在λ和2λ时则较低；对于40nm的ZnO微粒来说，超声波的频率为40kHz时，膜片的增重百分率W（％）最高。 |

| Abstract: | The feasibility of embedding 40 nm ZnO particles into porous materials by using ultrasonic and its influence factors are studied. Through investigations, it is proved that the higher the concentration of nanoparticle suspension, the higher the weight of embedding percentage （EPW）. However, the increasing trend of EPW will minish quickly when the concentration exceeds 1%. In addition, the longer the process time of ultrasonic, the higher the EPW. EPW is always higher when the distance between film and ultrasonic transducer is λ/2 and 3λ/2, and lower when the distance is λ and 2λ. For 40 nm ZnO particles, EPW of the film affected by the ultrasonic of 42 kHz reaches the maximum. |
