Overview
The glass transition temperature (Tg) is a critical concept in materials science, particularly for polymers. It marks the temperature range where polymers transition from a rigid, glassy state to a more flexible, rubbery state. Understanding Tg is essential for predicting how polymers will behave un...
Key Terms
Example: Plastic is a common polymer used in everyday items.
Example: When heating a polymer, it may reach its Tg and become flexible.
Example: Thermal behavior is crucial for understanding polymer performance.
Example: DSC can determine the Tg of a polymer sample.
Example: DMA helps in understanding the viscoelastic behavior of polymers.
Example: Plasticizers are often added to PVC to lower its Tg.
