Sea­weed clue to wet-re­sis­tant glue

DEMM Engineering & Manufacturing - - NEWS -

Univer­sity of Can­ter­bury post­grad­u­ate re­searcher An­ton Mather is in­ves­ti­gat­ing New Zealand sea­weed to see what lessons can be learned to pro­duce wet-re­sis­tant glue.

The bi­o­log­i­cal sci­ences stu­dent is in­ves­ti­gat­ing sea­weed bio-ad­he­sives that could ben­e­fit the ma­rine in­dus­try.

There is also po­ten­tial for the sea­weed-based ad­he­sives to be used in the bio­med­i­cal in­dus­try for re­pair of tis­sues in place of stitches.

“Sea­weed has an abil­ity to ad­here to ma­rine sur­faces and with­stand large tidal forces,” says Mather. “To avoid be­com­ing de­tached, this kelp pro­duces an ex­tremely strong wa­ter-re­sis­tant glue an­chor­ing it to the rocks. We are in­ter­ested in what this glue is made from and the mech­a­nism be­hind its pow­er­ful con­nec­tion with the sur­face.”

Pre­lim­i­nary ex­per­i­ments demon­strate that kelp is ef­fec­tive in stick­ing to glass sur­faces. Fur­ther tests will es­tab­lish if the sea­weed can at­tach firmly to plas­tic and metals.
