La «madera transparente» llegó para reemplazar al vidrio


Un equipo de investigadores del Departamento de Agricultura de Estados Unidos (USDA) dice haber desarrollado “madera transparente”, un material similar al vidrio hecho casi en su totalidad de árboles.

Según los científicos, esta innovación es más fuerte, más seguro, más rentable y térmicamente más eficiente que el vidrio, informó Futurism.

Aseguran que el gran problema del vidrio convencional es que es un aislante de mala calidad, especialmente en la configuración de un solo panel.

Producirlo también puede dejar una gran huella de carbono. La industria de la madera emite alrededor de 25,000 toneladas métricas por año en ese país, según una declaración reciente del USDA.

Proceso verde

En su artículo publicado en Journal of Advanced Functional Materials, los investigadores afirman que su madera transparente da como resultado ventanas cinco veces más térmicas que el vidrio.

El proceso de creación del material también es mucho más ecológico, aseguran los expertos. Por un lado, es fabricado con árboles de balsa provenientes de plantaciones sostenibles y de rápido crecimiento.

La madera se oxida en un baño de lejía especial y luego se empapa en un polímero sintético.

El material resultante no solo es transparente, sino que adquiere propiedades similares al plástico: puede resistir los impactos mucho mejor que el vidrio y tiende a doblarse y astillarse como la madera, en lugar de romperse en pedazos.

“Con todos estos beneficios potenciales para los consumidores, la fabricación y el medio ambiente, las propiedades de la madera transparente no pueden ser más claras”, se lee en el comunicado entregado por USDA.
