NIST developed a new structure is made from wood pulp and Marine organisms of NIST developed composite materials made from wood pulp and Marine life new structure of composite material

a few days ago, the U. S. national institute of standards and technology ( NIST） A team developed a from wood and invasive Marine invertebrate life combined with a new type of composite material, its can improve material in food packaging, biomedical devices such as design, construction and transportation applications. The study is published in the journal of advanced functional materials, researchers will the derivatives of wood pulp and dry capsule combined with biological, preparation with flexible, sustainable, non-toxic and uv reflection properties of new type of composite material.
the project's initial inspiration comes from the super tough natural composites containing Buligand structure, which is very common in the natural design of materials. In this structure, due to any force impact driven by nanoscale twists and turns into a series of alternate curve, molecular layers in the rotation of microstructure, elastic crack, for enabling energy is a deflection, to maintain the structure and function of the whole of the material.
Jeff Gilman said: 'if develop suitable products, it can be used in the aerospace composite material to the fresh food packaging, etc. '
although Brigigand structure of wood is not natural, but by using acid pulp washing to remove lignin and amorphous cellulose, can produce dry emulsion solution to form a new material with the structure. In and of itself, these Buligand membrane is very fragile, and hard to bear the weight of the larger. However, when short of nano cellulose derivatives of wood rods and another has a long natural materials, the combination of the new material is strong and soft.
to do so, the researchers used a dry capsule, because they are made up of very long and high crystallization of nano cellulose, which is distinct from wood in a shorter crystal. The port and dock in warm areas often found that there are a large number of tunica creatures, one of them for the Asian dishes. The capsule of bio here is caught in western France, where they are seen as pests.
through the test of composite material, can determine the biggest toughness tangent point indeed. Join the tunica biological means nanocrystalline distortion in different ways, and increase the structure formation of wood pulp, get closer and more compact structure, make the material has uv reflective. As project leader Jeff NIST composites Gilman pointed out: 'many materials if long-term exposure to the sun will begin to degrade, so the material could be used as a coating on the surface of the other, by the reflected light and extending material durability. '
the team will continue to explore the new way of blending to produce composite materials used in industry. As Jeff Gilman says, 'if develop suitable products, it can be used in the aerospace composite material to the fresh food packaging, etc. 'Conversion table packaging printing knowledge
