Talk:Nano tape

Safety

Has there been any research into the safety of nano fibers? I keep fearing that they’ll turn out to be like asbestos Skysong263 (talk) 16:00, 16 August 2023 (UTC)

Unlikely. Asbestosis is caused by free floating nano fibers from pipe or block insulation or improperly made asbestos cement products. The problem and cause are well understood and researched. Mwmahlberg (talk) 20:00, 29 December 2023 (UTC)

Studies have found its not gecko, but glue that makes this type of tape sticky.

Recent experimental research of commercially available product claiming to be "gecko tape" has determined that it's not the gecko-inspired structures that make it stick - they are there, but they don't contribute. Gecko/nano tape as available to consumers is NOT a "dry" adhesive, is a backing coated with a polyurethane glue, and it DOES leave residue behind. Regardless of whether or not academia has accomplished a true vandewaals force adhesive in a lab, the stuff being peddled to consumers is more gimmick than gecko. 2601:189:4180:33C6:CA0F:46B0:B809:D9E (talk) 22:27, 19 September 2023 (UTC)

See this 2021 study from Amsterdam:

"Nevertheless, a piece of gecko tape features a much higher work of adhesion than a piece of conventional adhesive tape of similar size."

This seems to be contradicting you. Also, your assertion of left behind residue is not supported by the study you mentioned.

The conclusion of the study, suggesting that the additional adhesion comes from the stiffness of the backing material is questionable at best. By that logic, if I back some adhesive tape with say some BASF Ultrafuse 316L, it gets stickier... Mwmahlberg (talk) 20:18, 29 December 2023 (UTC)
