    Yes. They are called electropolymers and were utilized in the
electrofabber once being developed by Ron Reitz of the US Navy. If you have
my book, see page 94 for more on this.

>or a plastic material that will float in water.

    Most plastics are slightly more dense than water, unless you form them
in a closed-cell foam. Anything can be made to float in water if it is
formed in a closed-cell foam that traps air or another gas, reducing the
overall density of the the system. Many grades of rubber and other polymeric
elastomers naturally float because their natural form is as a closed-cell
foam.
