> “Since ethanol is the main component of hand sanitizer, we believe it is possible to de-bond and recycle the adhesive by using hand sanitizer as a substitute in certain real-world situations,” Aida says.
These sorts of environmental impact blurbs are hilarious. What kind of scenario are they envisioning where someone wants to remove and reuse a specialized adhesive bonding PTFE parts to something, but don't have ethanol on hand and have to fall back to using hand sanitizer?
Who says this will be a specialized adhesive? If it works as advertised, it could be a super-glue alternative with easy unglueability. That would be an attractive consumer product; and the type of product that could easily end up on someones hands.
One example might be ungluing a lithium pouch cell (usually polyamide film outer surface, which is a pretty low-surface-energy polymer) for home replacement. Electrically-debonded adhesives are a better option here, but not sure what the cost trade-offs look like.
Hand sanitizer is also contaminated with other crap... presumably that impacts the adhesive if you're attempting to "recycle" it? I agree, what a weird line.
