MIT chemists design impact-resistant plastics
MIT chemists have developed a method to enhance the impact resistance of common polymers like polystyrene and rubber. By introducing weaker bonds as cross-linkers, these materials can better dissipate energy during impacts. This innovation could lead to improved applications in various industries, including packaging and electronics.
- ▪The new polymers can double the strength of traditional materials like polystyrene and rubber.
- ▪Weak bonds are introduced to allow the material to absorb energy more effectively during impacts.
- ▪The research team is exploring the potential for this method to be applied to other types of polymers.
