文摘
- •
A novel universal method is performed to enhance hydrophobicity of SiC/SiO2 powder.
- •
Through pyrolysis of KH570 and OP-7, hydrophilic groups is grafted.
- •
The hydrophobicity of SiC/SiO2-KH570-OP-7 was far superior to SiC/SiO2-KH570.
- •
A possible formation mechanism of hydrophilic surface was proposed.
- •
Surface changes on SiC/SiO2-KH570-OP-7 powder were analyzed via SEM, FTIR, XPS.
