- Preparation and characterization of covalently bonded PVA/Laponite/HAPI nanocomposite multilayer freestanding films by layer-by-layer assembly

Covalent bonding of nano-inorganics with polymers has a reinforcing effect on the physical and chemical properties of the materials. Hydrophilic aliphatic polyisocyanate (HAPI) was introduced to fabricate Layer-by-Layer multilayer nanocomposite films with inorganic nanoplatelets (Laponite) and polyvinyl alcohol (PVA). HAPI can covalently bond Laponite and PVA by the reaction between isocyanate and hydroxyl groups. The resulting films showed enhanced mechanical and optical properties compared with films without HAPI.

While flexible electronics have attracted great interest over the past few decades, much of the research has been focused on inorganic devices due to the relatively low environmental stability of organic materials. In this work, an electrical circuit composed of organic devices on a highly flexible, stretchable, and patchable freestanding polymeric substrate is realized. The results strongly suggest potential for the development of various stretchable and patchable devices and integrated circuits, which can lead to their further applications in many fields of science and engineering.
- Effects of aromatic regularity on the structure and conductivity of polyimide-poly(ethylene glycol) materials doped with ionic liquid

Article first published online: 13 JAN 2015 | DOI: 10.1002/polb.23664
Poly(ethylene glycol)-aromatic polyimide systems can vary in structure depending on the aromatic monomers and the synthesis solvent used. By using different aromatic dianhydrides, aromatic diamines, and synthesis solvent the amount and type of nanometer scale order can be tuned. These compositional and process changes manifest as structural variation which impact rigidity and ultimately conductivity by 30% or more with transport being inversely related to rigidity.
- Photorefractive performance of poly(triarylamine)-Based polymer composites: An approach from the photoconductive properties
Naoto Tsutsumi, Kenji Kinashi, Kento Masumura and Kenji Kono
Article first published online: 13 JAN 2015 | DOI: 10.1002/polb.23663
Methyl-substituted poly(triarylamine) based photorefractive (PR) composite gives high PR performance of diffraction efficiency 16.6% with response time 5 ms at 632 nm illumination with 1.5 W cm−1 and of higher diffraction efficiency 47% with response time 10.2 ms at 532 nm illumination with 0.427W cm−2. These enhanced PR responses are ascribed to the large photocurrent in the order of hundreds of μA.

Article first published online: 30 DEC 2014 | DOI: 10.1002/polb.23657
Carboxymethylcellulose (CMC), generally used as sodium salt NaCMC, is one of the most widely used polyelectrolyte cellulose derivatives. Significant questions regarding the local conformation and solubility of NaCMC in water remain unresolved. In this work, small angle neutron scattering (SANS) is employed to probe the solubility and conformation. These results are complemented by steady shear rheological measurements across a wide concentration range.
