Zwitterionic lignin derivatives for marine antifouling coatings

摘要

Disclosed are antifouling compositions that can include a biopolymeric matrix which is substantially zwitterionic. The compositions may include a biopolymer matrix having positively charged functional groups, negatively charged functional groups, zwitterionic functional groups, or a combination thereof, such that the composition is substantially zwitterionic. The compositions can be used as additives and as compositions further containing a base material such as paint or lacquer. Methods of making and using such compounds and compositions are also disclosed.

主权项

1. An anti-fouling coating composition comprising:
at least one biopolymer matrix comprising a lignin having one or more zwitterionic functional groups, one or more positively charged functional groups, and one or more negatively charged functional groups such that the composition is substantially zwitterionic.
