Polymers in solar cells, rubbers in soft robot, polymer composite in ISRO launch vehicle –these are some examples of cutting edge applications of polymeric materials. On the other hand, we see other examples of polymeric materials such as plastics and fiber reinforced plastics (FRP) all around us. What is so special about polymers, and why/how can they be used in such diverse applications? This course will introduce basic concepts related to polymeric materials; engineering estimations about their properties; various applications;and their impact on sustainability.INTENDED AUDIENCE :Students, practitioners and researchers who want to learn basics of polymersPREREQUISITES :First year courses in Maths, Physics and Chemistry, and Engineering ThermodynamicsINDUSTRIES SUPPORT :Plastics processors, FMCG companies,Automotive companies, Biotech firms
