The solution behavior and morphology of the nanostructures formed by novel block copolymers based on 1-cetyl[2-(acryloyloxy)ethyl]dimethylammonium bromide (ADHA) and 2-hydroxyethylacrylate (HEA) or N-isopropylacrylamide (NIPAM) have been studied using small angle X-ray scattering (SAXS), dynamic light scattering (DLS), and transmission electron microscopy (TEM). In these block copolymers the pADHA...
A two-stage synthesis has been developed for the first time to obtain montmorillonite–poly(1-methyl-4-vinylpyridinium) multilayers incorporated in polyacrylamide gels. Firstly, hexadecylpyridinium montmorillonite was entrapped in the polyacrylamide gel during polymerization. In the second stage the cationic surfactant was removed and replaced by alkylated poly(4-vinylpyridine). The products in each...
Magnetic gels are a new class of soft polymer materials with their properties controlled by magnetic fields. A method was developed for the preparation of magnetite nanoparticles in a matrix of poly(acrylamide) gel. Synthesis of the magnetic spinel iron oxide Fe 3 O 4 in a matrix of poly(acrylamide) gel was performed via coprecipitation of Fe(II) and Fe(III) in alkaline medium. The...
