*The 30:1 solution had a shifted wavelength (max absorption 529nm) due to the fact this solution was the only solution with color (see Figure below). Similarly, this was the only solution that did not form fibers. Fiber formation was observed beginning at 50:1 ratio(see Figure below). Varying ratios with smaller increments will be prepared to determine the optimum ratio for the preparation of fibers | *The 30:1 solution had a shifted wavelength (max absorption 529nm) due to the fact this solution was the only solution with color (see Figure below).
