| Abstract: |
| Using microcrystalline cellulose as raw material, cellulose stearoyl ester/10-undecyl ester (CSU) compound was synthesized by nucleophilic substitution, and the derived CSU micro/nanoparticles were prepared by nanoprecipitation. By spray-coating of the resulting micro/nanoparticles on the surface of silicon wafer which was impregnated with CSU solution, a reactive superhydrophobic surface was obtained. The nuclear magnetic resonance spectrometer (NMR), Fourier transform infrared spectrometer (FT-IR), Zeta potential analyzer (DLS), scanning electron microscope (SEM), and thiol-ene click chemical reaction system were used to characterize CSU and the superhydrophobic surface coated with CSU. The superhydrophobic mechanism, thermal stability and reactivity of this surface were mainly investigated. Results showed that the average diameter of CSU micro/nanoparticles was about (149±3) nm, the polydispersity index (PDI) was 0.132; the contact angle of the generated superhydrophobic surface was (153±1)°, and the sliding angle was 7°; its superhydrophobicity was unstable when temperature was above 40℃, and it could be further functionalized by the photoclick thiol-ene reaction. |
