Polymer Journal #4


Each of our prototypes were very similar in material and characteristics. Prototype 1 was made using Gloop and liquid starch, our second prototype was made using liquid starch and solid cornstarch. We combined the two by having prototype 1 as the inner layer and prototype 2 as the outer layer. Since our first two prototypes melted while being in a closed system, we remade three more polymers. The first one (#3) was Stretchtastic, then adding guar gum and corn starch. The second one (#4) was Gloop mixed with liquid starch and solid cornstarch. The last one (#5) was Gloop mixed with liquid starch. All of these prototypes were tested in an open system, to figure out which polymer is best used as the inner layer of our product. After all prototypes were tested, we thought prototype #5 worked the best. For the outer layer, we used prototype #3, but kept it in a closed system to keep the moisture and softness. The limitation of this product is that every time, we needed to detach the two polymers or else they will either both melt in a closed system or harden in an opened system. Prototype #5 worked the best for the inner layer because when it hardens, it holds its shape and is durable. It is also easy to attach and detach without staining or damaging the table or the polymer itself. Prototype #3 was the best outer layer because it is sticky and moldable enough to be able to cover the hard shell, while being thick enough to round up the sharp edges. Our product also included hangers that were attached to the bottom. We decided to use pipe cleaners because we weren’t able to make a polymer that was best used as hangers. Also, if the hardened polymer were to be attached to a polymer that was kept in a closed system, it will melt and soften overtime. Using the pipe cleaners, we found that it was easy to attach and shape. By twisting two pipe cleaners together, it became more durable and stiff. Throughout the Polymer Project I learned the different ways each polymer is made and what material causes the polymer’s physical properties to change. I also learnt the different characteristics each polymer has in both closed system and opened system and how it can benefit our goal of creating a table corner protector with an attached hanger.

Polymer Journal #3

For our polymer project, June, Evelyn and I made a polymer that was able to protect sharp table corners. We wanted a polymer that was sticky for it to hold onto the corners, thick enough to prevent injuries while being soft enough to be molded to the shapes desired. Our first prototype was made with the Gloop recipe then adding 2mL of liquid starch. This prototype was molded to a table corner for testing. Few days later, the polymer hardened and was similar to plastic. The polymer also became a lot thinner, but it was durable and could be reused without damaging furniture or the polymer itself. Since our first prototype became rough on the edges and no long had the protecting characteristics, we decided to cover it with another polymer made with the same materials but adding a scoop of solid cornstarch. We covered the previous polymer with the new one we created and tested it. We tested our second prototype by attaching it to the table corners. Since the inner layer of the polymer was hard, it was easy to attach and detach it while having a soft outer layer to prevent injuries. However, when we stored the polymer in a closed system, it melted, so we had to start over using the same base materials. In class, we made three different polymers. Two of the polymers were the same as prototype 1 and 2. For the third polymer, we decided to make a Stretchtasitic.  All three of them were moldable and were securely attached to the table corners for testing. As a ending result, our third prototypes will include the same characteristics as our first two prototypes; a hard shell that we will use as the inner layer and the soft and thick outer layer.

Our goal for the polymer project is to create a polymer that can improve furniture. We chose to combine two existing products into one, a hook that hangs objects and a rubber table corner protector. Our version is different because it has two different uses combined in one. The polymer will be molded  into a cat or dog shape, with its tail hanging down being used as a hook. This product is maily targeting parents, insuring their child’s safety. However, anyone can use this product to insure their own safety as sharp corners may cause injuries. This product will be able to reduce the chance of people getting injured by sharp corners while also being able to hang objects on it. Aesthetic wise, this product will be made out of the polymer ‘Gloop’, molding it into a cat and a dog, making it appealing to both kids and adults. This product will also be removable and reusable for it to be convenient to attach it to different furnitures. We think Gloop is the best polymer to make this product because it is soft enough to change the shape, while being firm enough to protect the corner and  durable for it to be able to hang heavy objects. However, we may need to incorporate other polymers into the original Gloop, incase the consistency is not the best for our goal of improving furniture. This polymer may need to be more stretchable as the Gloop breaks easily, so by combining Gloop and Stretchtastic, the polymer may work better for the use of this product.

Polymers are made out of monomers like ethylene and propylene, they are linked together to form long polymer chains. Synthetic materials are from materials based on polymers that are made from small molecules. Nylon, styrofoam and polyester are all examples of synthetic materials. The fibers are made by joining the monomers together, forming a polymer by going through a process called polymerization. Nylon goes through a chemical and manufacturing process that creates the fiber’s strong polymers then turning it into a durable fiber. Polyester fibers are formed from a chemical reaction between an acid and alcohol. Natural resources are something that’s natural and found in nature, this includes plants, a
nimals and wood. Rayon is a type of natural resource; it is a natural-based material that’s made from the cellulose of cotton. Society uses both Nylon and polyester in many ways. Both materials can be used to make clothing. Nylon can also be used to make ropes and hard plastic. Polyester can be used as industrial fabrics, recording tapes and computers. All of these items are used in our everyday lives. Synthetic and natural products are both made from natural resources found in nature that can also be changed by people. The difference is that the synthetic materials are man-made using the natural resources, then being changed chemically to produce a new substance.
