How to create medimer by daniel

 

 

Polymer Prototype #6 was our most successful prototype. After the polymer was made, it was a firm, smooth, sticky to itself, and very moldable. It had all the traits we needed for a medical polymer, in case we needed to wrap it around a finger, mold it as a cast, or stick it over a bruise for protection. We ran several tests on this, one it had to be sterile. We didn’t want mold growing on it or anything coming out of it that could infect any cuts or injuries. This was our residue test, our goal was to make it so the polymer kept to itself and did not leave any residue like liquid, color marks, or parts of itself. Prototype 6 passed this test, it was very clean and simple, it would be perfectly safe and sterile for injuries. Next, we wanted to test the firmness, if it was able to protect an injury. We tested this with one of my less favorite tests. I would get punched in the shoulder, and then have the polymer stuck there and get punched in the same spot. The polymer successfully reduced the pain from the punch evidently concluding that it was shockproof to a certain extent. Our last test was how long it would stick around injuries, this test made sure that the polymer could be used for longer durations. The injury we focused this test around was the jammed finger, we wrapped our polymer around the finger and bonded 2 fingers together to keep the injured finger still. We waited to see if the polymer would loosen up or slip off. It successfully maintained its latch to my fingers and provided its process for an entire class. Lastly, we obviously ran tests that benefitted customer satisfaction. We played around with the polymer for a long time, and it was not at all a mess, like I said, it was a firm smooth polymer that loved to stick with itself, but was good with not getting messy and sticking to everything else it touches. We also tested its sustainability, we wanted to see how many times we could reuse it for. For 4 classes, we put it on as a cast for 15 minutes and sealed it away, each time, the polymer worked correctly with no gradual defects as it aged. The guar gum is a galactomannan polysaccharide extract that alters the polymer to thicken and stabilize its current properties. This helps the polymer because according to an area of science called material science. The polymer itself has a lot of elasticity and firmness, but according to the physics of the polymer, it has a balanced range of elastic deformation and plastic deformation. This means that with relative smaller forces applied to the polymer, the polymer will rearrange back into its former shape, but if a more powerful force is applied, then it passes the plastic deformation point and causes permanent change. So this is technically not a nonnewtonian fluid, but its physical properties certainly differ from other slimes. This allows the polymer to wrap around fingers and at the same time hold its current shape. So to sum up, prototype 6 was our best polymer due to its functional physical properties, reliability, and customer satisfaction traits.

 

Overall, I think my team’s product pitch to the dream on team was successful. We addressed all parts needed: Originality, sustainability, and quality. If I were to do something different, I would probably try to be more prepared. It was my fault that i was unaware that the product pitch was on Tuesday and it caused me to hurry and not present my best. The whole polymer was pretty good, we successfully created a polymer that matched all traits and properties that we wanted. Maybe if we spent more time altering the traits, we could produce more types of the polymer for different purposes outside of the medical use. Our soft polymer did not have the most sustainable ingredients, it included 100 mL of PVA glue and 15 mL of borax, which are both not sustainable ingredients. The other ingredients are cornstarch and guar gum. Even though its not made of the most sustainable ingredients, we tested several times that it could be easily reused over and over, as long as once you were finished, you put it into a sealed bag. This makes the polymer more sustainable so you dont need to use wasteful ingredients everytime you make a new one. Lastly, our hardshell polymer is made of recycled polymers which is really sustainable.
