ABSTRACT: An interpenetrating polymer network (IPN)
hydrogel based on poly(propylene glycol) and poly(acrylic
acid) was prepared by UV irradiation. The swelling behavior
of the IPN hydrogel was studied by the immersion of the gel
in aqueous NaCl solutions of various concentrations. The
swelling ratio decreased with an increase in the NaCl concentration.
The electrically sensitive behavior of the IPN
hydrogel in electric .elds was also investigated. The IPN
hydrogel also showed a stepwise bending behavior that
depended on the electric stimulus. The bending angle and
bending speed of the IPN hydrogel were greatest in 0.6 wt %
aqueous NaCl and increased with an increase in the applied
voltage. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89:

It's very easy reading, so don't bee intimidated. Read it all, it's fucken solid.
=======================
I would bee so excited if someone would like to test this on either some locked up methamphetamine or overbased pseudo that has been trapped due to Orange beeing activated..
Hopefully the freebase will rise to the surface in the case of the psuedo freebase.
Use carbon electrodes (Grey-led pencils duh) and a battery to pass a current through the aqueous solution of locked up sudo.
The water should already contain enough ions to play with due to the (bungled) basification. Only add more NaCl after attempting the solution without adding any.
Another suggestion is to use a stop/start technique in your ground-breaking science, by this I mean simply stopping and starting the flow of electric current by switching it on and off.
If you notice fb surfacing don't stop, continue as you have been, because the hydrogels could still contain more of your sudo.
The reason I suggest starting and stopping is beecause the gist of it is that the Na ions displace the sudo within the hydrogel entrapments by weight of numbers. So imagine the pumping action on the gels, contract/dilate.
This is the “something” I found for ware. I did PM him regarding it but he hasn't replied, so I think it's best to leave him in peace with an empty mailbox...
