Fabric tear-resistant nanotechnology came out

According to foreign media reports, the Massachusetts Institute of Technology (MIT) recently developed a polymeric nanocomposite material with elasticity and strength characteristics of spider silk that can be applied to packaging materials, tear-resistant fabrics and biomedical devices. It is reported that the U.S. military is extremely interested in the application of this material in tear resistance or other body protection equipment and will provide research and development funding.

According to reports, researchers have developed a method to bury nanoclays in elastic polymers. In this method, after the clay particles are dissolved in water, the water is used as a solvent to dissolve the polyurethane, the polymer is dissolved, a new mixed material is formed, and finally the solvent is removed. The hardened granular nanoclay composites will be dispersed in a stronger and tougher elastic substrate. The flaky nanoclays are randomly distributed in the material, so the resulting nanocomposites are heated to temperatures above 150 degrees Celsius. Also very little deformation.

The U.S. military is more interested in using the nanocomposite to replace the heavy packaging used by the current US military ready-to-eat rations. In addition, fabric manufacturers also expressed interest in nanocomposites. The material can be made into elastic fibers like nylon fibers or leica.

The nanocomposite manufacturing method can also be applied to biocompatible polymers, and can be used to manufacture coronary stents used for cardiac catheterization surgery. Although engineers have been able to produce materials with elasticity or strength, it is still difficult to produce materials with both elasticity and strength.
