There was a heavy raft of work for perhaps a decade (maybe much longer) on polymer materials that have very acidic side-chains. I don’t know how anything like that behaves if it is out under air, rather than in a fluid environment. But if viruses are not dry, and are hosted in small droplets for a time, perhaps that distinction is less relevant.</div><div class=""><br class=""></div><div class="">In any case, considering that the glove industry is probably entirely predicated on reducing unit cost, and that I have no idea what the elasticity may be of fuel cell membrane polymers, they probably will not be glove material anytime soon. I haven’t even looked at that literature for, what, maybe 15 years (?). So I have no idea what the state of development is now.</div><div class=""><br class=""></div><div class="">Eric. <br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jun 23, 2020, at 3:38 AM, <<a href="mailto:thompnickson2@gmail.com" class="">thompnickson2@gmail.com</a>> <<a href="mailto:thompnickson2@gmail.com" class="">thompnickson2@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="WordSection1" style="page: WordSection1; caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Any materials experts out there?<span class="Apple-converted-space"> </span><o:p class=""></o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Ok, so.
