TEHRAN (INIC) -- Researchers from Kashan University, Iran, succeeded in the production of fireproof coatings by synthesizing a type of magnetic nanoparticle and using it in a nanocomposite structure.

Fireproof is a term used for a wide range of chemicals that are added to synthetic materials, including plastics, fabrics and coatings. These materials prevent the extension of flame by stopping a number of chemical reactions in the flame and creating a protecting layer on the surface. These materials may combine with the matrix or create a chemical bond with it.

Non-toxic Replacement for Usual Fireproof Materials

This research introduces an effective non-toxic replacement for the usual fireproof materials such as carcinogenic aromatics containing halogens as the filler of polyvinyl alcohol. Polyvinyl alcohol is a commonly-used polymer with many applications in various industries. Relatively low resistance to heat and high flammability are the main disadvantages of this polymer.

Usual fillers weaken the mechanical properties of polyvinyl alcohol due to the inappropriate dispersion and the creation of two-phase structure. The application of nanoparticles and creation of nanocomposite structure prevents this problem, and it decreases the rate of polymer degradation against heat.

Iron oxide magnetic nanoparticles have been firstly synthesized through simple chemical deposition method, and the effects of various parameters, including concentration and ratio were studied on the morphology of nanoparticles. Then, nanoparticles were produced through in-situ polymerization in aqueous solution of polyvinyl alcohol without the need for atmosphere. Fire resistance and late burning tests were finally carried out.

About INIC

Iran Nanotechnology Initiative Council (INIC) was established in the country in 2003.The INIC is tasked with determining the general policies for the development of nanotechnology in the country and pursuing the case with implementation of the policies.
