Figure 2.

Air contact angle measured in distilled water on polypropylene (PP) substrates modified with (a) different CB random copolymers, and (b) PCB1–37 at different concentrations. Number stands for the molar ratio of two units in copolymers, e.g., 28 in PCB1–28 indicates that the molar ratio of CB/BMA in this copolymer is 2/8. Single asterisk (*) in (a) indicates statistically significant difference (p < 0.05, n = 5) compared to PCB1–37; and single asterisk (*) in (b) indicates statistically significant difference (p < 0.05, n = 5) compared to 0.50 wt%.
