Table 3 The relation between ∆Eab and identification ability of human vision.
From: Poplar-based thermochromic composites that change colour at 38 °C to 46 °C
∆Eab | Human vision |
|---|---|
0–0.5 | Unnoticeable change |
0.5–1.5 | Slight change |
1.5–3.0 | Appreciable change |
3.0–6.0 | Recognition change |
6.0–12.0 | Obvious change |
> 12.0 | Very obvious change |
