“…Besides compositional effects, the substrate can also impact the behavior of epoxy‐acrylate materials during curing, or during service periods. For example, barrier properties against water or oxygen are important physical factors for the overall material substrate protection, and this protection is directly related to the crosslink network density . As discussed by He et al, an increase in the crosslink density of the cured samples can be expected when samples are exposed to certain degradation environments resulting from initially unreacted fractions of reactive groups in the coating.…”

Chiu et al compared polycarbonate (PC), poly(vinyl chloride) (PVC), and glass as substrates for UV‐curable organic/inorganic hybrid composite coatings, and observed that coated PC films had more light transmittance than PVC or glass, suggesting that the substrate properties must be considered with the overall system.…”

During radiation curing, a reactive formulation is converted into a highly crosslinked coating film by means of polymerization reactions. This three‐dimensional (3D) network is resistant to external degrading factors as it cannot be undone by any physical–chemical means. In this study, various ultraviolet (UV)‐curable ink formulations with different pigments were developed. The behavior of the UV‐curable inks was evaluated during UV curing in a photocalorimeter or in a UV tunnel. Inks were exposed to accelerated aging in an accelerated weathering chamber and their physical–chemical properties were investigated. The presence of residual fractions of unreacted species trapped in the 3D network formed during UV curing interferes with the degradation of the main structure during exposure in the weathering chamber. The ink formulations that did not easily absorb UV light increased in gloss and hardness, indicating that residual crosslinking is taking place at the same time that degradation is occurring. © 2014 Wiley Periodicals, Inc.

Vinyl group contained silica (MSiO 2 ) nanoparticles were prepared by co-condensation of tetraethoxysilane (TEOS) with 3methacryloxypropyltrimethoxysilane (MPS) and applied in miniemulsion polymerization of methyl methacrylate (MMA), butyl acrylate (BA) and 1H,1H,2H,2Hheptadecafluorodecyl methacrylate (FA) to prepare fluorinated polyacrylate/silica nanocomposite particles. Morphology and particle size of MSiO 2 was characterized by scanning electron microscopy (SEM). The nanocomposite films were investigated by atomic force microscopy (AFM), Fourier transform infrared spectroscopy (FT-IR), water contact angle, visible light spectroscopy, X-ray photoelectron spectroscopy (XPS) and thermogravimetry (TGA) analyses. Effect of MSiO 2 amount on surface properties of nanocomposite films were studied. Results showed that MSiO 2 nanoparticles presented rough surface with a mean particle size of 200 nm. The nanocomposite film showed high transparency and surface hydrophobicity of the fluorinated polyacrylate film was increased significantly by incorporation of 0.04 g (0.46 wt.% of monomers) of MSiO 2 nanoparticles. The presence of MSiO 2 contributed to surface enrichment of Please do not adjust margins Please do not adjust margins fluorinated components, and the nanocomposite film formation mechanism was proposed.

“…One of the most noticeable selections for chemical modification is use of hyperbranched polymers which has been conducted by several researchers. 7,8 Decrease in viscosity and generation a fractal structure has been of the most features of such polymeric compounds. The corrosion and mechanical properties can be also improved by having the hyperbranched chemical structures.…”

Two different approaches were used to modify a UV-curing resin based on polyester chemistry, namely molecular and nano-particular approaches. In the molecular approach a hydrophobic compound, glycidyl neodecanoate, was reacted with the resin and was fixed on the polymer backbone. In the nano-particular approach a nano-clay was used to modify the resin in a physical manner. The electrochemical properties of the coating films were investigated using electrochemical impedance spectroscopy. In all cases a broadening of the complex plane graph in the direction of real impedance axis was observed. It was necessary in all cases to incorporate a finite length warburg element into the equivalent circuit to account for this broadening effect. The presence of this element was attributed to an intermediate case of anomalous diffusion of charge carriers through the dense polymeric network of the UV-cured films. EIS investigations of the UV-cured films show that both molecular and nano-particular modifications cause the electrochemical properties of the film to remain constant for a longer immersion time compared to unmodified resin.
