Conductive bilayer polymer films formed by polyaniline and polymeric ionic conductor

Conductive bilayer polymer films based on polymer electrolyte and polyaniline have been prepared by the electrochemical polymerization of aniline on an electrode covered with an ionic conductive polymer film. Electrochemical polymerization was carried out by the potentiodynamic method. The electrochemical properties of the bilayer films were investigated by cyclic voltammetry. The cyclic voltammograms indicated that the bilayer films have good redox stability, as well as reversibility, and show electrochemical activity in the solid state at room temperature. An all-solid-state rechargeable battery composed of lithium and this bilayer polymer film was tested. The preliminary experimental results showed that the battery can discharge in moderate electric current. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 66: 525–536, 1997     

Effect of block compositions of amphiphilic block copolymers on the physicochemical properties of polymeric micelles

Amphiphilic block copolymers with various chain lengths of poly(n-butyl methacrylate) blocks (PBMA) and poly(N-acryloylmorpholine) blocks (PAM) were prepared by RAFT polymerization. Packing parameter of block polymers in water (β < 0.2) indicated the formation of core-corona structures, which was further confirmed from a difference between core- and corona-forming chain surface areas. Hydrodynamic micellar size was related with the numbers of BMA (N_BMA) and AM (N_AM), and their ratios (N_BMA/N_AM). With increasing N_BMA/N_AM value, the polymer aggregation numbers and inner core sizes increased, while the critical micelle concentrations, the corona thickness, and the second virial coefficient of block copolymer micelles decreased. These properties changed with increasing N_BMA/N_AM value resulted in a linear increase in corona chain unit density (ρ_AM) that limited chain mobility. Thus, the interaction between the micelles and serum protein at low ρ_AM disappeared at a higher value. Consequently, both micellar properties and biocompatible effect can be regulated by tailoring the block compositions of amphiphilic polymers.     

Use of photodegradable inhibitors in UV-curable compositions to form polymeric 2D-structures by visible light

The process of two-wave photopolymerization of a UV-curable composition with an optically degrading inhibitor is considered. By numerical simulation, it is shown that in the composition layer uniformly exposed to UV-radiation, such systems allow getting segments with different conversion under the action of inhomogeneous visible light. Based on the data on the photopolymerization kinetics of the compositions from triethylene glycol dimethacrylate (TEGDMA) and bisphenol-A glycidyl dimethacrylate (bis-GMA) with the UV-initiator 2,2-dimethoxy-2-phenylacetophenone (DMPA), it was shown that 3,5-di-tert-butyl-o-benzoquinone (35Q) with N,N-dimethylaniline (DMA, “Aldrich”, 99%) can serve as an inhibitor that degrades under action of visible radiation. Combining inhomogeneous visible light generated with a conventional DLP-projector and uniform UV-radiation of LED (365 nm) the two-wave lithographic process was implemented to create polymeric 2D-structures in 20 μm layer of the compositions from TEGDMA (70)/bis-GMA (30)/DMPA (0.05 wt%)/35Q (0.5 wt%)/DMA (1 wt%).
