Experiment: Synthesis of Biodegradable Plastic from Cornstarch
Significance:
Plastic pollution is a major environmental problem, and biodegradable plastics are a promising solution. This experiment demonstrates the synthesis of biodegradable plastic from cornstarch, a renewable resource.
Materials:
Cornstarch Vinegar
Glycerol Water
Plastic wrap Microwave
Procedure:
1. Mix cornstarch and water: In a bowl, mix 2 tablespoons of cornstarch with 1/2 cup of water until a thick paste forms.
2. Add vinegar and glycerol: Add 1 tablespoon of vinegar and 1 teaspoon of glycerol to the paste and stir until well combined.
3. Microwave the mixture: Microwave the mixture for 30 seconds on high power, or until it forms a dough-like consistency.
4. Knead the dough: Remove the dough from the microwave and knead it on plastic wrap to prevent sticking. Continue kneading until it becomes smooth and shiny.
5. Form the plastic: Shape the dough into any desired shape, such as a film or a container.
6. Let it dry: Place the plastic on a paper towel and let it dry overnight or until it becomes hard and brittle.
Observations:
Before microwaving, the mixture is a thick paste. After microwaving, the mixture transforms into a dough-like consistency.
When kneaded, the dough becomes smooth and shiny. The final product is a biodegradable plastic that is hard and brittle.
Conclusion:
This experiment demonstrates the synthesis of biodegradable plastic from cornstarch, a renewable resource. The plastic is biodegradable because it is made from natural materials that can be broken down by microorganisms. This type of plastic has the potential to reduce plastic pollution and promote sustainability.
