Iran produces nano-coatings to protect aircraft bodies

TEHRAN, Jan. 23 (MNA) – Iranian researchers produced special nanostructured coatings that can be used in aircraft bodies to protect them against heat, INIC reports.

According to Iran Nanotechnology Initiative Council (INIC), Iranian researchers have produced special nanostructured coatings that can be used in aircraft bodies to protect them against heat.

The advantage of these coatings over normal coatings is their ultra light weight. The research has been carried out at the laboratorial scale and the results have applications in aerospace systems and sustainable energies.

Coatings were synthesized in this research by using magnetic nanoporous pigments made of iron oxide, and their application was evaluated in the protection of aircraft bodies by carrying out various tests.

Based on the results, magnetic nanoporous pigments synthesized in this research have appropriate structure and they have better light sorption to emission ratio than conventional industrial pigments or even carbon black. In other words, the ratio in the synthesized sample is closer to one in comparison with that in usual samples; therefore, these products are highly good options to be used in the production of thermal coatings in aircrafts.

According to the researchers, weight is an important parameter in designing aircrafts and aerospace systems. In this research, the weight of pigment is decreased due to the application of nanoporous pigments. This fact finally results in a decrease in the weight of the final system. In addition, the concentration of pigment used in the structure is less than the critical volume concentration of the pigment due to the presence of nanopores in the structure. Therefore, a better performance of the coating has been observed in general tests such as abrasion, adhesion and bending tests.

The research findings can be used in low-orbit space systems, solar collectors and energy production sources.

Results of the research have been published in Journal of Coatings Technology and Research, vol. 12, issue 6, 2015, pp. 1065-1071.
