CHY 123 Modern Materials Polymers and Hydro gels Introduction Polymers and hydro gels and becoming more important in our everyday lives. Polymers are chains of monomers linked together multiple times. Polymers can be found naturally or made synthetically via the combination of the proper chemicals such as the ones we will be used today. Hydro gels are becoming very important in the medical industry, as they are able to absorb large amounts of liquid, which is perfect for bandages and such. These molecules have properties that allow them to absorb large quantities of liquid by suspending the liquid within solid frame that keeps the area around the hydro gel damp but not wet. Procedures We gathered the materials needed for the experiment and then put 25ml of the Hexamethylenediamine solution into the petri dish with a few drops of the phenolphthalein indicator and then slowly added 25ml of the sebacoyl to the petri dish as well. We then took a small wooden stick, put it in the solution, and started to turn it to gather the forming nylon. We
