FYP 2 Reflection of Progress 2

Summarize and explain the obtained result

Raman Analysis

Figure 1: G-Paper

I(D)/I(G)=75/350=0.214 (Multi layer Graphene)

Figure 2: Acidic G/PANI-Paper

I(D)/I(G)=300/2600=0.115 (Multi layer Graphene)

Figure 3: Non-Acidic G/PANI-Paper

I(D)/I(G)=240/1600=0.15 (Multi layer Graphene)

   The main features in the Raman spectra of carbons are the so-called G and D peaks which correspond to the edges and defects of the sp2 domains as well as the E2g mode for sp2 carbon domains of graphite. Single, Double, Few & Multi Layer Graphene can be determined by the Peak Position, Peak Intensity, and Peak Broadening of the Raman Spectra. From the Figure, the G-paper, Acidic G/PANI-Paper, and Non-Acidic G/PANI-Paper are  Multilayer graphene. The electrodeposition of PANI nanowire networks doesn’t effect the graphene layer.

Electrical properties Analysis 

   Based on the table, the PANI nanowire networks enhance the electrical performance of the capacitor.
