| Abstract: |
| In order to change the hydrophobic property of β-calcium metaphosphate whisker ( β-CMPW) , the surface characteristics of the whiskers were modified by octamethyl cyclotetrasiloxane ( D4) and triethoxyvinylsilane ( A-151) under the condition of ultrasonic. The hydrophobic property of the whiskers was determined by the wetting experiment. The factors such as the ultrasonic time, kinds and amounts of silane coupling reagent were analyzed by SEM, TG-DSC techniques. The results show that the hydrophobicity of β-CMPW unmodified is worse than the whisker modified by D4 0r A-151. 2% D4 is chosen as the optirmal silane coupling reagent and the ultrasonic time is 20 min. |
