Disclosed herein are coating compositions and methods of making and using the same. The coating composition includes a first polymer having at least one positively charged group; a second polymer having at least one negatively charged group; and at least one protecting group contacting the positively charged group of the first polymer, the negatively charged group of the second polymer, or both. The protecting group is configured to be removed by photocleavage to form a salt bridge between the positively and negatively charged groups. The coating composition may be hydrophilic when the salt bridge is formed. |
