The coating consists of one of: (i) a polymeric ionic liquid; or (ii) a VEC polymer formed from vinyl ethylene carbonate; or (iii) a homo-polymer formed from ethylene glycol methyl ether methacrylate, triethylene glycol methyl ether methacrylate, or polyethylene glycol methyl ether methacrylate; or (iv) a combination of any two or more of (i), (ii), and (iii). |
