Efficacy of Gold Photothermal-Activated Shape Memory Polyurethane

Table 2

Recovery as a function of recovery temperature. Recovery ratio is actual recovery divided by the recovery observed at 60°C for the pure PU sample.

Recovery temperature (°C)	Recovery ratio
	Pure film	0.32 ppm
60	1.00	1.00
50	0.89	0.92
45	0.86	0.88
40	0.83	0.84
