Lightness (L), chroma, hue and opacity (T) value of nanocomposite polymer film and control chitosan film.
| Types of Films | L * | a * | b * | C * | h° | T (Opacity) |
|---|---|---|---|---|---|---|
| Control chitosan | 27.58 ± 0.82 a | −0.45 ± 0.07 b | 2.36 ± 0.18 b | 2.35 ± 0.07 b | 100.89 ± 0.33 c | 1.95 ± 0.03 b |
| Chitosan-CuO NPs | 25.55 ± 1.28 b | −0.88 ± 0.09 a | 1.23 ± 0.04 c | 1.54 ± 0.09 c | 125.47 ± 0.36 a | 2.01 ± 0.06 a |
