Comparison of R₁ values obtained by FTIR-ATR analysis as function of DCP content for fibers of 1 mm raw and extracted from biocomposite PHBHV₉₅MIS₅ (samples 1 and 3).

Sample	PHBHVxMIS1−x	DCP (wt %)	${\mathit{R}}_{\mathbf{1}}=\frac{{\mathit{I}}_{1726{\mathbf{cm}}^{-1}}}{{\mathit{I}}_{1604{\mathbf{cm}}^{-1}}}$
	MIS100	--	1.3 ± 0.01
1	PHBHV95MIS5	0	1.3 ± 0.01
2	PHBHV95MIS5	0.25	1.6 ± 0.02
3	PHBHV95MIS5	2.20	3.4 ± 0.04
