Viscoelastic Properties of Water-Absorbed Poly(methyl methacrylate) Doped with Lithium Salts with Various Anions.

ABSTRACT: We investigated the effects of water absorption on the dynamic mechanical properties of poly(methyl methacrylate) doped with various generic lithium salts, such as lithium perchlorate trihydrate (LiClO₄), lithium trifluoromethanesulfonate (LiCF₃SO₃), lithium nonafluorobutanesulfonate (LiC₄F₉SO₃), and lithium bis(trifluoromethanesulfonyl)imide (LiN(CF₃SO₂)). The rates of weight change during water absorption of lithium salt-doped samples were higher in the following order: LiClO₄, LiCF₃SO₃, LiC₄F₉SO₃, and LiN(CF₃SO₂). Interestingly, the aforementioned order was the same as the order of the terminal relaxation times in
