Peculiarities of photonic crystal recording in functional polymer nanocomposites by multibeam interference holography

Abstract

Two-dimensional photonic crystal structures (PCS) were fabricated using a one-step recording process, multi-beam interference in smart polymer nanocomposites incorporating SiO2 and Au nanoparticles sensitized to 532 nm laser radiation. It was shown, that PCS with different geometry can be recorded in thick nanocomposite layers. The typical two dimensional (2D) PCS have square structure with 2-8 µm period, being in good agreement with theoretical structures obtained by mathematical modeling of the recorded PCS. The peculiarities of the photo-polymerization of nanocomposites with plasmonic Au nanoparticles were analyzed on the basis of Surface Plasmon Resonance Imaging (SPRi) and Raman spectroscopy investigations and used for the interpretation of the recording process and periodic structure formation.

“…It leads to a harder and more hydrophobic surface than the initial one. [40][41][42] The addition of ZnONPs and TiO 2 NPs has not influenced essentially the measured values. However, as there was a difference in composition, in structure and in the parameters, it may influence the interaction with the microorganism.…”

“…This tendency can be connected with the process of photopolymerization, which was studied in some previous papers. [40][41][42] The added monomers (IDA, 2Car) led to a lower rate of photopolymerization process, which resulted in a softer and more hydrophilic surface. The addition of AuNP to the mixture of monomers in all cases leads to higher microhardness and contact angle value.…”

“…Акриловые среды этого типа, содержащие наночастицы SiO 2 , а так-же Au, оказались пригодными для изготовления двумер-ных фотонных кристаллов [81]. Показана возможность создания оптической памяти с помощью толстослойных фотополимеризующихся регистрирующих сред, содер-жащих наночастицы SiO 2 и тиольные композиции [82].…”

Polymer–chalcogenide glass nanocomposites for amplitude–phase modulated optical relief recording

“…For example, combining polymer and quartz glass nanoparticles results new, flexible glassomer-type material [3]. Polymer nanocomposites containing organic and inorganic components were developed and applied for optical, holographic recording of different photonic elements like gratings, two-or even three dimensional structures [4][5][6][7][8]. The limiting factors for optical application of these materials may be connected with high scattering levels, which essentially decrease at comparatively low concentrations and sub-wavelength, nanometer-scale dimensions of NPs [9].…”
