通过接触角测定仪来表征样品羧基化CGO的亲水性。样品制备步骤:测试前将CGO粉末在10 MPa下通过台式粉末压片机压缩10分钟,形成薄而平坦的薄膜从而进行测试。
The hydrophilicity of sample carboxylated CGO is characterized by contact angle analyzer. Sample preparation steps: CDO powder is compressed at 10 MPa by a benchtop powder press for 10 minutes for 10 minutes before testing to form a thin, flat film for testing.
