I used 1-3 % PANI-EB in my scaffolds and measure contact angle of them, finally saw that my data didn't show any significant change.
Dear Mohammad Mohammadi :
PANI-EB and Gelatin-based scaffold surface have the same polarity or surface tension. Therefore, the contact angle is not changed. See Young's equation.
Best regards.
Thank's a lot dear Yuri Mirgord for your guidance.
I have been using paraffin, but the deposited ZnO still detach from electrode. What is the best binder to modify graphite paste electrode with ZnO nanoparticles?
