Layer-by-Layer Self-Assembly of Reactive Polyelectrolytes for Robust Multilayer Patterning

Fabrication of Multilayered Nanoporous Poly(methyl silsesquioxane)

“…A promising technique for multilayer assemblies is the layer-by-layer self-assembly method reported by Decher et al [5,6] Since their demonstration of multilayer structures based on electrostatic attractions between the charged polymeric species, numerous studies have focused on the properties of multilayers of various materials and their potential applications. By using differential solubilities induced by UV exposure or selective deposition depending on ionic content, patterned multilayers have been demonstrated by Clark et al and Shi et al [7,8] Recently, Caruso et al [9] reported the fabrication of multilayers of hollow inorganic silica with diameters ranging between 720 and 1000 nm by layer-by-layer deposition of silica nanoparticles and polymers onto colloids, and subsequently removing the colloid template. These porous materials are envisioned to provide new and exciting applications in areas of chemistry, biotechnology, and materials science.…”

Fabrication of Stable Chiral Polyaniline Nanocomposite‐Based Patterns

“…The ability of a DR molecule to form hydrogen bonds with -COOH under acidic conditions has been verified, [3] and the hydrogen bond formed from DR molecule can be converted into a covalent bond under UV irradiation. [19,20] The surface of the CPANs prepared in the presence of poly(acrylic acid) is carboxyl-rich, therefore, it is reasonable to consider that the hydrogen-bonding interaction is the driving force in the CPAN/DR spin-assembly process.…”

“…[1][2][3] In particular, ultrathin film patterns have attracted a lot of attention owing to their promising applications in different areas such as microanalysis, tissue engineering, and microelectronic and micro-optic devices. [4][5][6][7] Some technologies have been developed to form ultrathin films with specific patterns such as photolithography, soft-lithography, electron-beam etching, capillary force lithography, nanoimprint lithography, embossing, micro-molding, cold welding, microcutting and others.…”

Fabrication of covalently linked PAH/PVS layer-by-layer assembled multilayers via a post-photochemical cross-linking strategy

“…Currently, the LbL technique has attracted tremendous attention for its simplicity, universality and precise control of thickness at the nanoscale, and has been widely applied in various promising research areas, including chemical sensors and biosensors [4] , stimuli-responsive micelles [5] , enzyme immobilization [6] , surface patterning [7][8][9] , controlled drug release systems [10] , photoelectrochemically active electrodes [11] , separation membranes [12] , microporous films [13] , surface-imprinted multilayers [14] , erasable films [15,16] and even macroscopic supramolecular assembly [17] . However, LbL assembled multilayers have been traditionally fabricated based on the weak electrostatic attraction of the interlayers [18][19][20] and the driving force of supramolecular interactions or other weak intermolecular interactions, which are unstable in some rigorous situations, such as high/low pH values, high ionic strength conditions or solutions with disturbances, for example under sonication [2] .…”
