Characterisation of mesoporous polymer films deposited using lyotropic liquid crystal templating

摘要: Porous polymer films show interesting properties as ion selective membranes. In this work, poly(1,2-diaminobenzene) and polytyramine were deposited from hexagonal liquid crystal templates using two different surfactants. Resulting investigated to find evidence of mesoporous structures. While templated has already been described charge in the past, electrochemical experiments work demonstrate that another mechanism (most likely, size selectivity) also contributes its behaviour. Films characterised spectroscopic ellipsometry impedance spectroscopy. Results provide further for porosity, thinness, presence ions films. It is demonstrated use a low-cost surfactant (Brij 56) sufficient templating process. contrast, gave no being by crystal.
