Synthesis and characterization of liquid crystalline polyacrylates and non-liquid crystalline polypyrroles from bifunctional monomers

Water in different poly(styrene sulfonic acid)‐grafted fluoropolymers

“…These results showed that layered nanostructures of ionized side‐chain LC polymers function as two‐dimensional ion conductors as shown in Figure 6. Previously, functional moieties such as ion‐ and electroactive moieties were introduced into the side‐chain LC polymers to induce anisotropic function 41–44. For example, a thienyl moiety of the side‐chain LC polymer was polymerized to give a poly(thiophene) structure 43.…”

For example, a thienyl moiety of the side‐chain LC polymer was polymerized to give a poly(thiophene) structure 43. However, no macroscopic orientation could be achieved for these preorganized side‐chain polymers because of slow motion and entanglement of polymers.…”

Synthesis and Characterization of Liquid Crystalline Alkylammonium Polyacrylates

“…Similar results were also found for nonionic acrylic monomers having hexyl or decyl chains, which exhibited an undefined smectic phase upon heating, while the corresponding polymers showed a smectic A phase on the cooling run. [23] The data presented in Table 1 show that, in spite of the small difference between the side chains size, the values of isotropization enthalpy (PA-1: 23.46 J/g) and (PA-2: 49.0 J/g) deviate from the expected behavior. At a first glance, the isotropization enthalpy of PA-2 can be accounted for by a higher degree of molecular order and stability of the LC state as compared to PA-1.…”
