Study Notes

Biodegradable Polymers

Biodegradable polymers break down naturally in the environment, typically through the action of microorganisms.
They degrade over time, reducing plastic waste and minimizing its impact on the ecosystem.
Applications include:
- Face masks
- Food packaging
- Sanitary napkins

Smart Polymers

Smart polymers change their properties in response to changes in their environment, such as temperature, pH, light, or electrical signals.
They can adapt to different conditions, making them useful for:
- Biomedical devices
- Sensors
- Self-healing materials

Nanocomposites

Nanocomposites are materials that combine traditional polymers with nanoparticles.
Nanoparticles are tiny particles with sizes in the range of 1-100 nanometers.
These materials are used for applications including:
- Energy storage
- Catalysis
- Biomedical devices
