The obtained oligomer was characterized by Fourier transform infrared and proton nuclear magnetic resonance (1H NMR) spectroscopies, and gel permeation chromatography, respectively. Then, the UV-cured free films of the modified CAB oligomers were investigated in terms of thermal degradation, physicochemical, wettability, and mechanical properties. The chemical modification process was performed in various percentages; then, the contribution of the unreacted hydroxyl groups of CAB on the wettability, thermal degradation, and air/water vapor permeability properties were all investigated. The mechanical properties, thermal stability, and surface wettability character of pure CAB were improved with TDI-HEMA adduct modification. Electrospinning was used to obtain a fibrous layer in order to search the air/water vapor permeability properties. Modification of CAB caused decline in air/water vapor barrier character and thus enhanced the permeability properties.

UV-curable coatings were cured under a high-pressure mercury lamp. The curing behavior and coating performance of the UV-curable coatings that were cured using 2-hydroxy-2-methyl-1-phenyl-propan-l-one or 1-hydroxy-cyclohexyl-phenyl-ketone were superior to those of the UV-curable coatings cured using bis (2,4,6-trimethylbenzoyl)-phenylphosphine oxide or diphenyl (2,4,6-trimethylbenzoyl)-phosphine oxide, when the UV-curable coating was cured in air.

Energy cure has been making great strides in recent years. According to a BASF study reported at RadTech Europe 2005 the high growth enjoyed by the radiation-curable market over the last 10 years is predicted to remain more or less unchecked until 2015, averaging 8-9% annually in Europe and NAFTA and 12-13% in Asia. UV (ultraviolet) and EB (electron beam) curable technologies have been expanding due to recognition of their so-called e/5 potential : efficient, enabling, economical, energy saving, enviro-friendly.Note de contenu : - Complex surface UV curing

SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.
Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Nanosilica was modified and functionalized with acrylsilane by the “grafting to” method via different grafting steps, i.e., prepared-grafting step and step-wise propagation. The prepared-grafting step was achieved by grafting the nanosilica surface with the prepared acrylsilane, which was obtained by thiol-ene click reaction between 3-mercaptopropyl trimethoxysilane (MPTMS) and trimethylolpropane triacrylate (TMPTA). The step-wise propagation was achieved by first grafting MPTMS onto the nanosilica surface and then using the mercapto groups as initiators to react with TMPTA. The acrylsilane was characterized by FTIR. The modified nanosilica was characterized by FTIR, TGA, and contact angle analysis. It was demonstrated that the thiol-ene click reaction can easily occur between MPTMS and TMPTA. The grafting ratio of modified nanosilica via prepared-grafting step was higher than that of step-wise propagation. The SEM images of fractured films containing modified nanosilica also indicated that the former is more effective than the latter in reducing the self-aggregation of nanosilica. The effects of modified nanosilica on the viscosity and hardness of UV-curable coatings were also investigated.
