Team Cavitation! This blog has been designed to keep a daily log of progress and also to share ideas and generate a focus for our experimentation. I (Anthony) will be checking the blog during my independent study and will work with any suggestions given. Let's get to work!

Alcohol Question
Mrs. Contant has found that we were right that 1-Octanol was the same as the 2-ethylhexanol. However, the differences are small therefore we can expect similar results in our test polymers. The only thing is that, as they called it, a penetrating odor. But once we get our own ballistics we can begin testing that as well.

Are you guys trying some of the block copolymer materials that Chelsea gave to you? If so, did she go over some of the materials preparation steps?
ReplyDeleteYes! WE have made 4 blocks (each at two different concentrations) of both the A-copolymer and the B-copolymer. We had to use a different alcohol than that mentioned in the articles you supplied. However with research we found out that we had a very similar alcohol and that will hopefully be useful when we begin to test them.
ReplyDeletesorry about the caps locks* and also we didnt have any instruction on how to prepare these polymers except the weight percent of each solution. Therefore I just made my own setup and followed as much information i could understand from the article. (also we had one concentration exactly the same, however do to lab mistakes (i forgot to subtract one of the original measurements) I got a different concentration and it seems to me that this solution could be something useful. We will find out when we begin our testing.
