Effects of BPO on Boron Nitride UK 5 and 10 in Water and in Heptane

Effects of BPO on Boron Nitride UK 5 and UK 10 in

WaterQui Nguyen

Repeat the experiment using BPO because the BPO I used last time was contaminated.

Procedure

- 4.4 mg of Boron Nitride- 5 mL of water- 15 mg of BPO- Bath sonicated for 30 minutes

Thin film

I tried to make the thin film using the same procedure from Steve, but this time I did not dilute the PVDF solution. The thin film came out better, thicker, and stronger; however, the thin film shrinked. I was able to measure the conductivity of the thin film, and it was about 5.6-7.8 MΩ.

Thin film

- 6 mg of G3243- 5 mL of Heptane- 5 mL of water- used around 2 mL of PVDF

Future work

I’m going to try casting different concentration of the PVDF on the thin film. The thin film I made the first time was too thin, and the second time was thick but it shrinked. I think It will be better if I try to dilute a different amount of PVDF in DMAC.
