(a) Water contact angle (WCA) measurement of the PDMS and functionalized PDMS strip. (b) Fourier Transform infrared (FTIR) spectra of the PDMS (green line), PDMS-vinyl (red line) and PDMS-SMs (black line). (c) Effects of SMs modified PDMS on friction coefficient. The SMs were assembled on the surface of PDMS by covalent bonds (black line) or physical adsorption (red line); (d) X-ray photoelectron spectroscopy (XPS) survey spectrum of the SMs-AgNPs (insert: Ag 3d spectrum).
