aCalculations based on contact angles from bromonaphthalene, formamide, and water for insoluble collagen (100 μg/mL).
bCalculations based on contact angles from bromonaphthalene, formamide, and water for soluble collagen (100 μg/mL) in phosphate buffer solution (1x, pH = 7.4).
cCalculations based on contact angles from bromonaphthalene, dimethylsulfoxide, and water.
dObtaining a smooth coating without smearing or orange peeling was difficult and may have contributed to an anomalous/inaccurate surface energy profile; however, for completeness, the surface energy profile for
3b was included in the dataset.
