Wet adhesion remains a challenging task to humans, while nature has already found an answer to this problem. Sandcastle worms build a protective shell from sand grains or pieces of shell found in their surroundings, by gluing them together using an adhesive protein. Research has revealed that these adhesive proteins contain large amounts of charged and hydrophobic amino acids. In this research, we synthesize ABA triblock copolymers containing a charged middle block, flanked by temperature sensitive outer blocks. The polymers are synthesized using the controlled polymerization method reversible addition chain transfer (RAFT) polymerization. Polymers synthesized using RAFT display narrow polydispersities and well defined block lengths, which simplifies analysis and comparison of the underwater glues.
