  • Title : “Reversible CO2 Capture by Mesoporous Polymers and its Subsequent Conversion to Renewable Biodegradable Plastic: A Green Alternative to Petroleum-based Plastic Bottles and Other Polyester Products.”
  • Accounting code : DST Ref. No.: SB/S2/RJN-113/2016
  • Summary:
  • Most of the previous works dealing with CO2 capture used inorganic mesoporous materials and suffers from slow capture. On the other hand, most of the plastic products are made from a polymer called polyethylene terephthalate (PET), also known as polyester. Each year, around 50 million tons of PET is produced worldwide for making different items such as fabrics, electronics, recyclable beverage containers and personal-care products. The starting materials to make PET are terephthalic acid and ethylene glycol, which are derived from refined petroleum and natural gas. The use of fossil-fuel feedstocks, added with the energy required to manufacture PET, generates more than four tons of CO2 for every ton of PET that’s produced. In situ co-condensation strategy, followed by reversible deactivation radical polymerization (RDRP, earlier known as controlled radical polymerization) technique will be utilized to prepare the mesoporous materials. These studies will enhance our understanding of the mesoporous materials and will have considerable impact on developing new cost-effective technologies for CO2 capture and storage. Finally, CO2 will be utilized as a monomer along with other monomers derived from renewable sources to prepare biodegradable plastic. By using CO2 that would otherwise be emitted to the atmosphere, the process has the potential to cut CO2 emissions while simultaneously reducing petroleum consumption and producing useful products for Indian consumers. The CO2 containing polymers can be tailored for a diverse range of applications, including flexible, rigid, and microcellular packaging foams with higher tensile strength and load-bearing capacity, thermoplastics, and coating resins for food and beverage cans. This research is truly interdisciplinary and offers a unique opportunity for us to discuss with recognized scientists from the field of chemistry, physics and materials science. Such collaboration will significantly enhance the infrastructure for research and education in the country.
