Question

part 6. discussion and future work

1. a known characteristic of this paint is its low resistance to humidity. how could you control humidity when testing the paint?
2. there are over 200 different varieties of prickly pear cactus. how might the variety of cactus used for its polymer - containing goop influence the results?
3. what other factors may have influenced the results?
4. think of a set of questions that could help you further investigate the use of cactus goop as a paint binder.
5. what other formulations would you be interested in testing and why?

Explanation:

1. To control humidity when testing the paint, one could use a humidity - controlled chamber. This allows for precise regulation of the moisture levels in the testing environment.
2. Different varieties of prickly pear cactus may have different chemical compositions in their polymer - containing goop. This could lead to variations in paint properties such as adhesion, drying time, and durability.
3. Other factors influencing the results could include temperature during testing, the surface on which the paint is applied, and the application method (brush, spray, etc.).
4. Questions for further investigation could be: What is the optimal ratio of cactus goop to other paint components? How does the goop perform in different climates? What is its long - term stability?

Answer:

1. Use a humidity - controlled chamber.
2. Different chemical compositions may affect paint properties.
3. Temperature, surface, and application method.
4. Optimal ratio, performance in different climates, long - term stability.
