| 摘要 |
The invention concerns an item comprising a substrate having at least one main surface coated with a layer A in direct contact with a hydrophobic outer layer B, characterised in that said layer A has been obtained by depositing, under ion beam, activated species from at least one compound C, in gas form, containing, in the structure of same: at least one carbon atom, at least one hydrogen atom, at least one Si—X group, in which X is a hydroxy group or a hydrolysable group chosen from the H, halogen, alkoxy, aryloxy and acyloxy groups, —NR1R2 in which R1 and R2 separately designate a hydrogen atom, an alkyl group or an aryl group, and —N(R3)—Si in which R3 designates an alkyl group or an aryl group, said compound C being neither tetramethyldisiloxane nor tetraethoxysilane, nor vinylmethyldiethoxysilane, nor hexamethylcyclotrisilazane, said layer A not being formed from inorganic precursor compounds. |
