چکیده
|
The present research aims to combine rapid and modern laser drilling with loading octadecylamine (oda) to produce a hydrophobic polycarbonate/tio2 mesh. the laser drilling first created hierarchical microholes on the polycarbonate/tio2 film using ablation process. the polycarbonate/tio2 mesh was then immersed in oda solution. the morphological and structural investigation indicated that oda shells cover the pc-tio2 mesh surface. x-ray photoelectron spectroscopy (xps) was utilized for investigating the change in element/chemical state after laser drilling and oda treatment. the wettability of the produced polycarbonate/tio2 mesh was changed from hydrophilic to hydrophobic, in a way that the water contact angle was changed from 45 to 122.4°.
