Material characteristics of PLGA:CNF (wt%:wt%) looking at (A) wettability of the material at different PLGA density ratios, indicating that all materials are hydrophobic. (B) Example of material conductivity at a PLGA density of 0.025 g/mL, providing evidence of an inverse relationship between PLGA ratio (wt%) and material conductivity.
Notes: Conductivity data are expressed as the mean ± standard deviation (n = 3). *P < 0.05 versus 100:0 (PLGA:CNF [wt%:wt%]) ratio; **P < 0.05 versus (PLGA:CNF [wt%:wt%]) ratio; ***P < 0.05 versus 50:50 (PLGA:CNF [wt%:wt%]) ratio, and ****P < 0.05 versus 25:75 (PLGA:CNF [wt%:wt%]) ratio.
Abbreviations: CNF, carbon nanofibers; PLGA, poly(lactic-co-glycolic-acid).
