Abstract

Abstract High-energy radiation preferentially degrades cellulose and enriches lignin content at wood surfaces particularly in hardwoods. Accordingly, we hypothesize that a similar effect will occur at surfaces exposed to plasma. We test this hypothesis by plasma-treating pine and poplar veneers and assessing changes in the lignin and holocellulose-derived sugar-content of veneers; quantifying etching of pellets containing lignin and cellulose, and observing etching of different cell wall layers in pine and Homalium. The majority but not all of our results support our hypothesis. Lignin-rich regions of wood cell walls were easier to see after plasma treatment. We discuss the potential uses of plasma-etching for the study of wood ultrastructure and the creation of wood surfaces with self-bonding properties, and conclude that plasma-etching can be used as an alternative to chemical pretreatments for ultrastructural studies of the distribution of lignin in wood cell walls.

用氧辉光放电等离子体对软木和硬木表面进行化学和形态修饰
高能辐射优先降解木材表面的纤维素和丰富木质素含量,特别是在硬木中。因此,我们假设在暴露于等离子体的表面也会发生类似的效应。我们通过等离子体处理松木和杨木贴面并评估贴面木质素和全息纤维素衍生糖含量的变化来验证这一假设;定量测定含木质素和纤维素颗粒的蚀刻,并观察松木和Homalium不同细胞壁层的蚀刻情况。大多数但不是全部的结果都支持我们的假设。等离子体处理后,木材细胞壁的富木质素区更容易看到。我们讨论了等离子体刻蚀在木材超微结构研究和具有自结合特性的木材表面创造方面的潜在用途,并得出结论,等离子体刻蚀可以作为化学预处理的替代方法,用于木材细胞壁中木质素分布的超微结构研究。

期刊介绍: The Journal of Wood Chemistry and Technology (JWCT) is focused on the rapid publication of research advances in the chemistry of bio-based materials and products, including all aspects of wood-based polymers, chemicals, materials, and technology. JWCT provides an international forum for researchers and manufacturers working in wood-based biopolymers and chemicals, synthesis and characterization, as well as the chemistry of biomass conversion and utilization. JWCT primarily publishes original research papers and communications, and occasionally invited review articles and special issues. Special issues must summarize and analyze state-of-the-art developments within the field of biomass chemistry, or be in tribute to the career of a distinguished researcher. If you wish to suggest a special issue for the Journal, please email the Editor-in-Chief a detailed proposal that includes the topic, a list of potential contributors, and a time-line.
