“…42) in the DMF solution increased with the sustained light irradiation, indicating that the proposed photoinitiating system (i.e. dye 9/Iod/TEA) could reduce Ag + to AgNPs (as shown in Scheme 3c, 43,44 ). During the irradiation process, the color of the solution changed from light yellow to dark yellow, and a coating of silver nanoparticles was visible on one side of the cuvette after 100 min of light irradiation (see Fig.…”

“…In paper [4], a study of nanocomposites based on acrylates with combined effects of photopolymerization in the presence of plasmonic fields of gold nanoparticles was carried out. Article [5] shows that for all nanocomposite films containing metal nanoparticles, the permittivity and dielectric losses are about 50 times higher than for polymer films. In work [6], a study was made of cubic optical nonlinearities for multilayer nanocomposites based on aluminum oxide with different concentrations and sizes of nanoparticles.…”

The paper shows that nanocomposite materials based on a dielectric matrix with metal nanoparticles uniformly distributed in it can serve as a reference material in surface plasmon resonance spectroscopy. At certain concentrations of nanoparticles, such a nanocomposite, in contrast to the nanoparticles themselves, acquires the properties of a resonant material in which the real part of the complex permittivity takes negative values and, thus, the nanocomposite becomes surface-active. Surface plasmon polaritons can be excited at its boundary. For this reason, such a nanocomposite can be used as a reference material, similarly to the silver layer used, in the analysis of the optical properties of samples by surface plasmon resonance spectroscopy. The case of circular polarization of light incident on the structure under study is considered. The analysis of ellipsometric parameters of reflected light is carried out. The high sensitivity of the method is shown. In the range of incidence angles of 35° - 55°, the most pronounced angular dependence of the ellipsometry parameters is observed. Taking into account the analysis carried out, it is possible to suggest using these patterns in SPR spectroscopy to analyze materials in a structure containing a layer of the material under study and nanocomposites as reference elements, against which a sharp extremes of reflected light appears.

“…Photoinduced polymerization has become a versatile strategy for synthesis of polymers and manufacturing of materials − widely used in coatings, photoresists, adhesives, and 3D printing . Photopolymers integrated with rich functional fillers may render fresh performance to the polymers, spanning from high mechanical properties and dielectric properties, refractive index, and electrical conductivity as well as multiple stimuli responsiveness. − The functionalities of photopolymers are significantly improved with the increase of filler content. However, composite fillers often absorb, refract, or scatter incident light, leading to the increase in the light-attenuation gradient. , Such extinction behaviors, especially in the case of a high filler content, intensively weaken the light penetration through the entire polymerizable medium and inhibits photopolymerization; these eventually lead to the deterioration of material performances, and therefore photopolymerization of highly filled systems remains a profound challenge .…”

Filling Aggregation-Induced Extinction Mechanism in Near-Infrared Photopolymerization for Gradient and Highly Filled Bulk Materials

et al. 2022

The efficiency and curing depth of filled photopolymerization considerably depend on light penetration that is affected by filler extinction behaviors. In this study, the underlying mechanism of filling aggregation-induced extinction (FAiE) utilizing low-absorption and high-dissipation (scattering and refraction) fillers for improved light penetration in upconversion materials-assisted nearinfrared photopolymerization (UCAP) is reported. Results revealed that the extinction mechanism depends on the relationship between filler characteristic size (S c ) and incident-light wavelength (λ i = 980 nm). When S c < λ i , the filler extinction performance was gradually strengthened with the increase in the filler content, and high filling further induced spontaneous aggregation of filler, resulting in the growing S c . The highest extinction was observed at S c = λ i and then tended to be stable (S c > λ i ), which was mainly caused by a variable scattering intensity; this was lower than the extinction in the ideal dispersion state and was beneficial for highly filled photopolymerization. The extinction mechanism was theoretically evaluated by a light-attenuation gradient model and experimentally confirmed by different S c particles coupled with an electron microscope as well as polymerization kinetics test. Moreover, the extra "promotion effect" for functional-group conversion and mechanical properties of materials via the dissipation light of the fillers was demonstrated, and the exploitation of such characteristics realized the preparation of multidimensional gradient materials. The established model integrated with FAiE in UCAP provides a theoretical foundation to successfully fabricate centimeter-level objects with 92% filling in a few minutes, highlighting the potential applications of UCAP technology in ultrahighly filled material manufacturing.
