In this study, the raw material of Japanese cypress wood (Platycladus orientalis (Linn.) Franco) was used and subjected to a series of treatment, including replacement of the water in wood by organic solvent, liquid UV-curable coating impregnation, surface coating removal, and UV curing. By this method, we innovatively produced a new type of transparent wood film which we refer to as “wood-texture transparent wood” (WTTW). WTTW retained the color, texture, and tactility of wood, while exhibiting a high transmittance of light and haze. Macroscopic and microscopic tests demonstrated that by removing the excess coating on the impregnated wood film surface, the microstructure and roughness of the wood surface could be successfully preserved, and the wood-like tactility of WTTW could be realized. WTTW exhibits better properties than those of the original wood, including a maximum light transmittance of 72.3 %, a haze of 72.3 % (at 550 nm), a tensile strength of 123.90 MPa in the longitudinal direction, a tensile strength of 6.64 MPa in the cross direction, and a hardness of 81.8 HD. In comparison to the traditional transparent wood, WTTW not only streamlines the preparation process, but also preserves the original wood texture, which aligns more closely with the tenets of green environmental protection and is more suitable for home decoration and privacy protection.

一种防紫外线的透明木膜，保留了天然木材的纹理和触觉特性


本研究以日本柏木（Platycladus orientalis (Linn.) Franco）为原料，经过一系列处理，包括用有机溶剂置换木材中的水分、液体UV固化涂料浸渍、表面涂覆等。去除和紫外线固化。通过这种方法，我们创新性地生产出了一种新型的透明木膜，我们称之为“木纹透明木”（WTTW）。 WTTW保留了木材的颜色、纹理和触感，同时表现出高透光率和雾度。宏观和微观测试表明，通过去除浸渍木膜表面多余的涂层，可以成功保留木材表面的微观结构和粗糙度，并且可以实现WTTW的仿木触感。 WTTW表现出比原木更好的性能，最大透光率为72.3%，雾度为72.3%（550 nm），纵向拉伸强度为123.90 MPa，横向拉伸强度为6.64 MPa。横向，硬度为81.8 HD。与传统的透明木材相比，WTTW不仅简化了制备过程，而且保留了木材原有的纹理，更符合绿色环保的宗旨，更适合家居装饰和隐私保护。
