Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="mame201300333-sec-0001" sec-type="section"> <p>Surface resistivity (<italic>ρ</italic>_s) of polyurethane (PU) films is reduced from 2.1 × 10¹² to 9.4 × 10¹⁰ ohm sq⁻¹ by addition of 1‐butyl‐3‐methylimidazolium bis(trifluoromethanesulfonyl)imide ([C₄mim][Tf₂N]) for only 10 ppm. Addition of [Tf₂N]‐type ionic liquids (ILs) for 1 000 ppm leads to the reduction of not only <italic>ρ</italic>_s from 10¹² to 10⁹ ohm sq⁻¹ but also volume resistivity (<italic>ρ</italic>_v) from 10⁹ to 10⁷ ohm cm, suggesting that the ILs are uniformly incorporated into the PU films. These PU films have <italic>ρ</italic>_s in the order of 10⁹ ohm sq⁻¹ even after methanol washing. The antistatic effects are attributed to ionic conductivity of the PU films, which is achieved by low glass transition temperatures of both PU films and [Tf₂N]‐type ILs. These results suggest that [Tf₂N]‐type ILs are excellent antistatic agents for PUs.<inline-graphic xlink:href="ark:/27927/pghqpm6nvc" content-type="mame201300333-gra-0001" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </sec> </abstract>
