A sulfobetaine zwitterionic compound, N,N-dimethylamino ethyl carbamate propyl triethoxysilane sulfonate ( SiNNS ), was designed and synthesized and its composition and molecular structure were characterized by means of FTIR and 1 H NMR spectroscopy. Furthermore, the biomimetic surface imitating the chemical features of cellular outer membrane were constructed via the self-assembly of SiNNS molecules on the hydroxylated glass surface. The morphology structure, chemical composition and wettability of the prepared bi-omimetic surface were characterized by atomic force microscopy ( AFM), X-ray photoelectron spectroscopy (XPS) and contact angle measurement. The antifogging and antibacterial adhesion performances of the biomi-metic surface were investigated using an untreated glass surface as a control sample. The results indicate that the zwitterionic self-assembled biomimetic surface can possess superhydrophilicity with a water contact angle of 9. 2° and underwater superoleophobicity with an oil contact angle of 175. 6°. Compared to the corresponding control sample, the zwitterionic self-assembled biomimetic surface can exhibit an excellent antifogging property and an obvious antibacterial adhesion performance.
