Fig. 6: Growth-induced healing property of anti-counterfeiting coating.
From: Self-growth of programmable 2D- and 3D-coupling responsive coating for anti-counterfeiting
a Schematic illustration of growth-induced self-healing process and the corresponding photographs. One of the samples was dyed with MNEA. The scale bar is 0.5 cm. b Stress-strain curves of P0, growth-induced self-healing (P0-1: nTFEMA/nHFBA = 1/1, P0-2: nTFEMA/nHFBA = 2.5/1). c Optical photographs of artificial cups prepared by growth-induced self-healing. Cup body: P0, flower and handle: P0. The scale bar is 0.5 cm. Optical photographs of artificial cup (5.6 g) containing quartz (9.35 g) sand and water (8.0 g). The scale bar is 0.5 cm. d Fluorescence photographs of artificial cup before and after UV. The scale bar is 0.5 cm.
