FTIR second derivative spectra showing changes in protein secondary structure of CPA-GO adhesives prepared by exfoliating GO (1% w/w GO:canola protein) with different oxidation levels. CPA pH Control: 10% w/v canola protein adhesive at pH 12.0; CPA GO-A: 10% w/v canola protein adhesive with 1% w/w (GO/protein) GO-A, CPA GO-B: 10% w/v canola protein adhesive with 1% w/w (GO/protein) GO-B, and CPA GO-C: 10% w/v canola protein adhesive with 1% w/w (GO/protein) GO-C.
