Abstract
We will examine the technology challenge of how engineers are improving comfort and user friendliness of prosthetics, while maintaining durability. Athletes encounter issues while training with prosthetic limbs due to discomfort at the attachment site. Our key focus material system will be polymers, since most prosthetics are made mainly with different kinds of polymers. This project will raise the issues related to comfort and will emphasize the importance of a solution to society because it would help the disadvantaged live fuller, happier lifestyles. The problem we are interested in is the material of prosthetics; in this case, current materials constrain their efficiency. Our video will investigate the problems that current prosthetics have based on the materials that are being used for them. Specifically, attachment sites for prosthetic limbs are uncomfortable because the basic polymers are not agreeing with the biomaterials of the body. We will discuss how a porous high-density polymer will improve limb prosthetics overall. Porous polymer materials would enhance the lives of amputees by providing artificial body parts that agree much better with the human body. The research being done to alter a polymer's properties helps to expand our knowledge of what we learned in class. We will emphasize this by discussing the relationship between the process, structure, and properties of prosthetic polymers.

Aerogel as a Thermal Insulator

Our chosen technical challenge is the loss of energy due to poor insulators in building infrastructure. The problem with the insulators of todays buildings is that they are composed of materials that are not energy efficient in the long run. For starters, a typically large amount of material is needed for the insulators to even accomplish their task, compromising space in the building that is not necessary for its construction. Todays insulators also tend to be brittle, calling out for maintenance fees that make the tenure of the material to be expensive as well. Should a thermal insulator be inefficient in its duty, the more energy is needed for a building to stay warm or cold during the extreme seasonal temperatures occurring throughout the year. Energy unnecessarily spent compromises the source of where it is obtained from, depleting the already stretched energy sources demanded by humans worldwide.
Our chosen material will address many of these dilemmas in a unique and efficient way. Our chosen solution for the problem of insulation is the use of a green material named Aerogel. Aerogel is amazing for addressing thermal insulation because its composition almost nullifies almost all methods of heat transfer (convection, conduction, and radiation). This is due to the fact that the material is composed of 99.98% air, which is a terrible thermal conductor due to its properties as a gas. Aerogel also has other incredible properties such as being 500 times the strength of its counterpart silica aerogel. This could be because aerogel has certain polymers that support the silica chains within it, such as polyimide, along with interchain linking (networking). Aerogels are also extremely thin, hydrophobic, breathable, and fireproof, adding more properties that make it a desirable thermal insulator. The processing of aerogels is very costly, however, leading to expensive pricing for its acquisition. Although its cost may be exorbitant, aerogels astounding properties grants it much potential as a green building material in thermal insulation.
