One-Component Stilbene-Based Iodonium Photoinitiators with Increased Photoacid Quantum Yield for Cationic Vat 3D Printing

Macromolecules, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 17, 2024

New advanced iodonium salts based on stilbene chromophores with significantly improved photoinitiating properties are presented. The extended conjugated double bond system provides major improvement in quantum yield of superacid generation (up to 10 times higher compared benzylidene-based salts) while maintaining absorption UV-A and visible light. newly developed exhibit activity toward cationically polymerizable monomers such as cyclic epoxy (e.g., 3,4-epoxycyclohexylmethyl 3,4-epoxycyclohexane-carboxylate (CADE)), oxetanes bis[1-ethyl(3-oxetanyl)]methyl ether (OXT-221)) glycidyl diglycidyl bisphenol A (DGEBA)) under the irradiation by light-emitting diodes (LEDs) emitting at 365, 405 even 430 nm, no additives. Commonly used diaryliodonium photoinitiators inactive those wavelengths. Moreover, some new also able photoinitiate free radical photopolymerization acrylate monomers, trimethylolpropane triacrylate (TMPTA).

A Comparison of the Optical Properties of Fibre‐Based Luminescent Solar Concentrators and Transparent Wood Towards Sustainable Waveguides

Luminescence, Journal Year: 2025, Volume and Issue: 40(1)

Published: Jan. 1, 2025

ABSTRACT Aiming at net‐zero emissions, most international and national policies focus on sustainable development goals. Hence, there is an immediate need for replacing carbon‐intensive materials with biomaterials. In this respect, article presents a road‐map moving from polymeric to waveguides in optical devices. Previous reports indicate that luminescent fibres exhibit better photon concentrations of nearly 30%–33% higher than flat‐plate waveguides. It also verified the in‐out ratio increases by 3.44 times when waveguide geometry changed planar equivalent area fibre bundle same luminophore. Meanwhile, transparent wood (Twood) gaining attention as green alternative acrylic sheets. The structure function conforms well fibre‐based solar concentrators (LSCs). Therefore, it intriguing compare Twood intrinsic micro fibrillary interior LSC natural alternative. This review provides in‐depth analysis, emphasizing benefits associated challenges using cylindrical over LSCs. paper collects compares phenomenon light guiding LSCs Twood. important consider key points discussed here while making transition towards

Abstract Herein, we prepared the high‐strength polyurethane acrylate (PUA) composites by introducing γ‐methacryloxypropyltrimethoxysilane (γ‐MPS)‐modified SiO 2 (γ‐MPS‐SiO ) and hyperbranched unsaturated polyester (U102) into PUA utilizing digital light processing 3D printing technology. Fourier transform infrared, 1 H NMR, gel permeation chromatography provided evidence for preparation of γ‐MPS‐SiO . And U102 could improve dispersion particles in PUA, which is conducive to improving tensile strength, bending thermal stability composites. Compared with /PUA, /U102/PUA strength 32.73 MPa 62.48 can be obtained when content 10 wt%. The mechanical properties increased increase content. When 20 wt%, T 5% , 50% residue at 650°C are 36.81%, 2.31%, 122.17%, respectively. strengths were 103.67% 125.92%, This work provides a new way dispersibility inorganic nanoparticles polymers photocurable resin products. Highlights A high‐performance has been synthesized. an excellent dispersing effect on synergistically improved polymer particles.
