UV-curing processes are used in industrial applications because of their advantages such as high-speed applications and solvent-free formulations at ambient temperature. UV-curable epoxy acrylate resins containing arylene ether sulfone linkages (EAAES) were synthesized through the condensation of bis(4-chlorophenyl)sulphone and bisphenol-A, followed by end-caping of epichlorohydrin and subsequently acrylic acid. UV-cured coatings were formulated with epoxy acrylates, reactive diluents such as pentaerythritol tri-acrylate and pentaerythritol dia-crylate and photoinitiator. Fourier transfer infrared, 1 H NMR, and thermal gravimetrical analysis were employed to investigate the structures and thermal properties of the EAs films. The introduction of EAAES into epoxy acrylate substantially improves its thermal properties and thermo-oxidative stability at high temperatures. In addition, the acrylate containing arylene ether sulfone linkages can also improve pencil hardness and chemical and solvent resistance of the epoxy acrylate. The obtained UV-curable epoxy acrylate containing arylene ether sulfone linkages is promising as oligomer for UV-curable coatings, inks, and adhesives in some high-tech regions.

Polymer blends and composite films were facilely prepared from their aqueous solutions with varying contents of poly(3,4-ethylenedioxythiophene) (PEDOT), polyethylene oxide (PEO), and polyacrylic acid (PAA). The physicochemical and electric properties of the composite films were analyzed by Raman spectra, infrared spectra (FT-IR), scanning electronic microscopy (SEM), thermogravimetric analysis (TGA), and four-point probe method. PEDOT was successfully incorporated into each blend which was confirmed by spectra analysis. The crystallization of PAA or PEO and the structure of PEDOT should be taken into consideration for the electronic conductivity. According to Raman spectra, in the case of PEDOT-PAA-PEO, conformation of the PEDOT backbone changed from the quinoid to the benzoid structure partly. The ionic conductivities of lithium-ion salt-mixed PAA-PEO and ternary blend were characterized by AC impedance spectroscopy. The ternary blend with LiCoO 2 presents good electronic and ionic conductivity, and it appears to be a new candidate for polymeric mixed ionic electronic conductor. POLYM. COMPOS., 36:2076-2083, 2015
