Polymer Physics podcasts

Melissa and Jam explain how hairspray combines a propellant, solvent and polymers to produce an aerosol that holds hair in place. The episode follows the formation of a fine mist, the behaviour of the polymer film and the formulation trade-offs involved, then compares hairspray with gels and mousses.

Melissa and Jam recount Stephanie Kwolek’s discovery of Kevlar and explain the polymer chemistry behind its strength. The discussion covers rigid aromatic structures, hydrogen bonding and the organization of polymer chains into strong fibres. It connects these molecular features with protective equipment and other applications.
