等离子体刻蚀并沉积类金刚石膜制备超疏水木材
Fabrication of superhydrophobic wood by plasma etching and deposition of diamond-like carbon films
摘要
Abstract
This study presents the fabrication of superhydrophobic wood of Acer saccharum Marsh. using a combination of O2 plasma etching and plasma deposition of a thin hydrophilic diamond⁃like carbon ( DLC) coating in order to impart wood with controlled wetting properties. The effect of O2 plasma etching on roughness was investigated using the scanning electron microscopy ( SEM) and laser scanning confocal microscope ( LSCM) profilometry. The wetting behavior was de⁃termined by the static water contact angle measurement. Furthermore, the morphology, thickness of deposited films, ele⁃ment composition and their chemical bonding information of the wood surfaces before and after the treatment were also examined with SEM, the ellipsometer and X-ray photoelectron spectroscopy ( XPS) . The results showed that the wood surfaces of the average roughness, root mean square roughness and peak⁃to⁃valley roughness increased with longer etching time within 30 min. However, the wood surface roughness decreased slightly after the prolonged etching time of 45 min. The static water contact angles of the wood surface increased firstly and then decreased with the increase of etch⁃ing time and attained a maximum value for 157�2° with 30 min etching and after depositing DLC film for 1�5 min, but the static water contact angle of the wood surface etched for 45 min and after depositing DLC film for the same time was 152�3° . The static water contact angles decreased gradually with an increase in deposition times if the wood surfaces were subjected to the same time etching. From the data of the deposition thickness, the deposition rate of DLC films was calculated, which was constant (51�7±4�5) nm/min over the deposition times investigated. The content of oxygen ele⁃ment reduced obviously and the diamond⁃like characteristic peaks of sp2-C and sp3-C presented after the wood surfaces deposited with the DLC film coating.关键词
