摘要

在本研究中，透明木材是通过使原巴尔沙木中的发色团失活，然后进行无溶剂脱水和随后的真空辅助聚合物渗透来制备的。透明木材的热降解主要分为两个步骤。研究了由轻木和丙烯酸聚合物制成的透明木材的光学性能(比色、透光率)。当样品厚度为0.7 mm时，光谱可见部分的透射率达到最大值。77%。厚度对透光率的依赖性随着木材厚度的增加呈线性降低。所创造的材料在可见和紫外光谱中也表现出吸收特性。

OPTICAL PROPERTIES OF TRANSPARENT WOOD PREPARED FROM BALSA

In this study, transparent wood was prepared by deactivating chromophore groups in raw balsa wood, followed by solvent free dehydration and a subsequent vacuum-assisted polymer infiltration. Thermal degradation of transparent wood takes place in two main steps.Optical properties (colorimetry, transmittance) of transparent wood made from balsa wood and acrylic polymers were studied. Highest values of transmittance in the visible part of spectra were achieved by 0.7 mm thick samples at approx. 77%. The dependence of thickness ontransmittance showed a linear decrease with increasing thickness of transparent wood. Thecreated material also exhibits absorbing properties in visible and UV spectra.
