In the past few decades, different kinds of flame retardant agents based on various chemical compounds have been employed to reduce flammability of polymers. Halogen based flame retardant agents are one of the most effective flame retardants. However, considering releasing of high smoke and corrosive gas, halogen based flame retardant agents have been gradually replaced by halogen-free flame retardants, which contain compounds such as phosphorus, silicon, nitrogen, minerals. To achieve a satisfied flame retardancy level, normally high loadings are required, which lead to negative effect on mechanical and thermal properties. With the arising of micro-engineered flame retardants, this problem has been solved. Due to the large interfacial area between polymers and nano-fillers, relatively low filler loading can lead to not only a significant reduction in PHRR (peak release rate), but also superior mechanical and physical properties. The aim of this project is to exploit novel micro-engineering technology with multi-functional flame retardants to imporve the flame retardency performance of polymer.
