. According to research conducted by MIT Research, through the use of nanocomposite materials it is possible to create coatings with greater scratch resistance, which is ideal for use in cars, cell phones and aquarium windows, because the addition of these small particles alter the properties of transparent plastic.
For the analysis, a polymer called poly (methyl methacrylate) or acrylate was used, frequently used as a substitute for glass and which can be fragile and much less resistant to tears than the latter. In this way, the group of MIT researchers found at the nanoscale a way to analyze the polymer particles of these coatings which would significantly facilitate their improvement.
Portions of silica were used for the trial to help preserve transparency in the final material. However, silica and acrylic are not compatible and there could be a agglutination of grains from the first material.
To overcome this, the researchers treated silica with other "functional groups" of molecules and changed its chemical surface. Then, to soften it slightly, they heated it and used a microscopic atomic force to help them observe how the particles slowly sank on the surface and thus be able to recognize how fast the process was that would lead them to determine exactly how the interaction occurred.
Finally with the result of the process, the team found the optimal state and density for the surface of the polymer since introducing a small amount of these particles increased the rigidity of the coating.
Thus, the specialists determined an approach for the study of fundamental chemistry and physical properties since, according to Mark VanLandingham, head of the Materials Response and Design Branch of the U.S. Army Research Laboratory, "thanks to this research many other works can be focused because there is an interest in understanding how these materials interact quantitatively in industry developments."
