摘要

为了探明放电活性粒子改性木材表面形貌和润湿特性及其机理

采用针-板电极产生正电晕和负电晕改性白松木表面

然后通过扫描电子显微镜、接触角测量仪、拉曼光谱仪和红外光谱仪分别获取参数

最后分析了放电处理后的白松木表面形貌、润湿特性和化学组成变化情况。研究表明

增加放电电压和作用时间

白松木表面的粗糙度和润湿性随之增加

纤维素和木质素的拉曼光谱强度随之减少

亲水基团的红外光谱强度随之增加;并且

放电处理后的白松木表面微观形貌、润湿特性和化学基团之间呈现关联特性。该研究为电晕放电改性木材表面的应用提供了有价值的参考。

Abstract

In order to explore the mechanism of both the surface morphology and wetting characteristics of wood that was modified by electric discharge active particles

a discharge plasma system with needle-plate electrode structure was used to modify the surface of white pine

which could be generated the positive and negative DC corona discharge. Then

parameters were examined by a scanning electron microscope（SEM）

contact angle measuring instrument

Raman spectrometer

and infrared spectrometer

respectively. Furthermore

the surface modification characteristics of the white pine wood including the surface morphology

wetting characteristics

and chemical groups were analyzed. Results show that

as both discharge voltage and treatment time for processing the white pine wood surface increase

the roughness and wettability will increase

the Raman spectrum intensity of the cellulose and lignin will decrease

and the infrared spectrum intensity of the hydrophilic group will increase. Additionally

on the white pine wood surface treated with discharge

there are strong correlation characteristics among the surface microscopic morphology

wetting characteristics

and chemical groups. This work provides a valuable reference for the applications of corona discharge in wood surface modification.
