TiO₂-Acrylate Nanocomposites Elaborated by UV-Curing with Tunable Properties

Abstract

Abstract. Homogeneous TiO2–acrylate nanocomposite with low optical scattering were prepared by UV curing. The surface of the nanoparticles was modified by carbonic acids to control the aggregation between the nanoparticles. Effects of TiO2 content on the properties of nanocomposite (transmission, refractive index, mechanical properties, internal structure) were investigated. Depending on the composition of the matrix hard materials with high refractive index or light sensitive layers for holographic recording can be obtained. The first are interesting for medical applications, the last for photonics. For example, TiO2 nanocomposite was used for in situ fabrication of holographic gratings by interference lithography. Formation of the grating samples with high diffraction efficiency (20 %) is based on the light-stimulated mass-transport processes in the polymerized layer during the recording without any additional treatments. The relief formation has been investigated by AFM measurements too. These materials are designed for applications in integrated optics, elements of optics, in nanolithography.

Recent Advances on Nanocomposite Resists With Design Functionality for Lithographic Microfabrication

“…Several classes of ceramic NPs and NWs have been used as fillers in NCMs, mostly based on transition metal oxides such as TiO 2 (An et al, 2012;Burunkova et al, 2013), ZrO 2 , HfO 2 (Bae et al, 2010), ZnO (Kandpal et al, 2012), silica (Hu et al, 2001;Jiguet et al, 2006b;Cho et al, 2006;Singh et al, 2011), BaTiO 3 (Xu and Wong, 2007;Kim et al, 2014;Marino et al, 2015b) and naturally occurring clays (Paul and Robeson, 2008). A common goal behind the addition of ceramic NFs is to reinforce mechanical properties of a PR (Tjong, 2006).…”

Synthesizing erbium and ytterbium oxide nanoparticles and obtaining luminescent polymeric composites based on them

“…The presence of such an active functional group ensures that the inorganic nanoparticles are compatible with the acrylate matrix. As investigated earlier, [10][11][12] it is because 2Car is present in the acrylate compositions that transparent and low-scattering polymeric composites are formed with the inorganic nanoparticles (SiO 2 , ZnO, etc.) with good optical and other operating properties.…”

Laser Light Durability and Nonlinear Optical Properties of Acrylate Polymer−Chalcogenide Glass−Gold Nanocomposites

“…Different NPs like SiO 2 , rare-Earth oxides, chalcogenide glasses (ChG), and Au NPs may be and were added to the acrylate matrix of investigated polymer NC films, as published in our previous papers. [6][7][8][9][10][11][12] The presence of ChG NPs introduces additional specific parameters like light-induced effects of variable optical transmission and refractive index. Au NPs are efficient plasmon generation sites, influencing the polymerization process and also the resulting parameters of the recorded photonic elements.…”

“…In the present paper, we performed investigations of the aforementioned problems for the selected row of previously developed urethaneÀacrylate NCs with silicon oxide, As 2 S 3 chalcogenide glass, and gold NPs, [6][7][8][9][10] with accent on high-intensity illuminations, necessary for possible applications in optical and photonic elements working at high laser intensities.…”
