![]() ![]() University of Maryland (UMD) scientists found that in addition to also owning a high haze factor, their epoxy-injected transparent wood became four to six times stronger than the original sample. A block of wood is made transparent by professors at the University of Maryland. Through their technique, the translucency of the wood can be altered by simply changing the ratio of wood to PMMA. Subtracting Opacity, Adding Strength and Versatilityīoth research teams arrived at wood with optical properties that made the samples transparent, though not perfectly so: The Swedish team, for example, achieved 85 light transmittance. ![]() That’s where the clear path to clear wood forked: Researchers at Sweden’s KTH Royal Institute of Technology mixed its substrate with prepolymerized methyl methacrylate (PMMA basically, acrylic glass), while a University of Maryland team injected its bleached wood with epoxy. When the lignin was pulled out of the wood fibers, the material left behind was milky in appearance-predictably white, but not yet transparent. Step one was to chemically remove lignin, which both contributes to the yellowish-brown appearance of wood and binds its cells and fibers together (helping give wood its trademark rigidity). The transparent wood is made by removing the lignin in the wood veneer. Within the last year, separate research teams using parallel methods have both advanced upon an idea that looks as incredible as it sounds: Transparent wood. If a group of Swedish and American scientists have their way, being able to “see the forest through the trees” could soon take on a near-literal meaning.
