Objectives: To explore polymers from renewable origin which has inherent higher thermal stability and flame retardancy for composite applications.
SERB Grant. No.: SB/FTP/ETA-0069/2014
Petrochemical based polymers and composite with flame retardants (FR) properties are important for wide range of applications such as advanced composite matrices, coatings, semiconductor packaging. Renewable sourced thermoset resins will mitigate accumulation of non-biodegradable waste and evolution of greenhouse gases during their processing and discard. In order to improve flame retardancy, conventional halogen and phosphorous based FRs are physically blended in polymer, and have a high global demand of 2.2 MMT in 2011, with a ~ 5% increase every year. Despite the effectiveness for halogenated resins in flame retardancy, they pose a possible threat to the environment and mankind due to release of highly toxic and potentially carcinogenic substances formation during combustion. Our work is to synthesise halogen free thermoset PBz resins based on agricultural biomass making a sustainable treat to the nature.
