Polyethylene oxide (PEO)‐like films were prepared by rf magnetron sputtering of PEO and by thermal evaporation of PEO with and without activation by argon plasma. Rf magnetron sputtering under low power (<10 W) leads to deposition of the films with significant loss of ether structure. Under higher power, a co‐evaporation regime is achieved and the resultant films are richer in ether groups. Thermal evaporation of PEO proves to be even more effective in retention of ether structure. The films evaporated without activation by plasma are very close in composition to original material, yet they are soluble in water. Activation of the flux of evaporated species by Ar plasma results in enhanced cross‐linking and better stability in water, however at expense of retention of PEO character.
