内容記述
内容記述 Polysiloxanes exhibit practical properties not observed in carbon or carbon–oxygen backbone polymers. Linear ionic polysiloxanes containing an amine hydrochloric salt exhibit a humidity-induced self-assembly (HiSA) behavior. HiSA leads to nanoscale structuring by the uptake of absorbed water around the ionic aggregates of the polymer, promoting the hydrophilic–hydrophobic phase separation of the polymer. The resulting polymer forms a self-assembled lamellar nanostructure with a period of ca. 1.6 nm. Herein, we investigate the factors affecting the HiSA behavior. Introducing a dimethylsiloxane unit into the ionic polysiloxane achieves a more ordered lamellar structure and improves the nanostructure stability at higher humidities. The flexibility of the polysiloxane backbone, formation of ionic aggregates, and hydrophilic–hydrophobic phase separation affect the HiSA behavior. This nanoscale assembly can be characterized as a lyotropic liquid crystal formed with the assistance of ion aggregation instead of the hydrophobic effect in aqueous systems of ordinary surfactants.
