Figure 2.
Effect of fluoroalkyl side chains on the structure and viscoelastic properties of the materials. (a) Experimental and simulated small-angle X-ray scattering patterns of the fluorinated elastomers. Simulations were performed according to the Yarusso–Cooper model51. (b) Differential scanning calorimetry traces of the fluorinated elastomers. The glass transition temperature (Tg) of each polymer is indicated with an arrow. (c) Effect of fluoroalkyl side chains on the temperature dependence of the storage modulus (E') and tanδ for the indicated polymers. (d) Temperature dependence of E' and tanδ for fluorinated poly(ethyl acrylate-random-methyl acrylate) PEMAxFy having different fluoroalkyl side chain lengths.
