A series of Norrish type I photoinitiators (NASs), which are naphthalimide aryl sulfide derivatives, prepared. The potential mechanism involved in the photolysis NASs under UV LED at 405 nm is investigated by steady-state photolysis, nuclear magnetic resonance, electron spin fluorescence spectroscopy, cyclic voltammetry, and laser flash calculating bond dissociation energies C–S bonds NASs. as-prepared NAS5 NAS6 can efficiently initiate free radical photopolymerization (methyl)acrylate...
Photocured materials with self-healing function have the merit of long lifetime and environmentally benign preparation process thus find potential applications in various fields. Herein, a novel imidazolium-containing photocurable monomer, (6-(3-(3(2-hydroxyethyl)-1H-imidazol-3-ium bromide)propanoyloxy)hexyl acrylate, IM-A), was designed synthesized. Self-healing polymers were prepared by fast photocuring IM-A, isobornyl 2-(2-ethoxyethoxy)ethyl 2-hydroxyethyl acrylate as monomers. The...
Eco-friendly brake friction composites with good performance were developed. The raw materials utilized selected according to eco-friendly criterion that natural products should be preferably chosen. formulations are composed of plant flax fiber, mineral basalt and wollastonite as reinforcements, graphite solid lubricant, zircon abrasive, vermiculite baryte functional space fillers, cardanol-based benzoxazine-toughened phenolic resin binder. To isolate the fibers, chemical physical methods...
Ternary nonfullerene all-small-molecule organic solar cells (NFSM-OSCs) were developed by incorporating a acceptor (IDIC) and two structurally similar small molecular donors (SM SM-Cl), where SM-Cl is novel donor derived from the reported SM. When doping 10% in SM:IDIC binary system, power conversion efficiency (PCE) of ternary cell was dramatically increased 9.39 to 10.29%. Characterization studies indicated that tend form an alloy state, which effectively down-shifted highest occupied...
A photosensitive silicone-containing polyurethane acrylate prepolymer (Si-IPDI-HEA) was synthesized and characterized adequately by FTIR, 1H NMR, GPC analyses. The effect of the monomers on photopolymerization kinetics Si-IPDI-HEA investigated real-time infrared spectroscopy (RT-IR). results showed that resin with common acrylic exhibited a high polymerization rate double-bond conversion. influence monomer silicone microstructure properties UV-cured film also systematically studied. It found...
The paper addresses utilization of 0–14.6 vol.% alkaline-treated walnut shell powders (WSPs) as a functional filler in the proposed eco-friendly brake friction materials. Five non-asbestos material samples containing WSP and jute fibers from biomass biodegradable components were prepared, also including several natural resources, such wollastonite, basalt fibers, zircon, barite, vermiculite. friction-wear properties prepared composites tested by using Chase performance testing device....
ABSTRACT Two benzoxazine precursors bearing carborane moiety ( 1 and 2 ) were designed synthesized successfully by the Mannich reaction of corresponding bisphenol 3 4 with aniline formaldehyde in 1,4‐dioxane. The obtained characterized using multiple spectroscopic techniques including GPC, FTIR, H NMR, 13 C 11 B NMR. Nonisothermal DSC studies showed that precursor owned lower apparent activation energies E a than . optimum curing processes also on basis data. TGA analyses manifested...
We designed and synthesized two novel fluorophenyl oxime ester photoinitiators (E-FBOXEs) with the ability to prepare photochromic polymers, then polymers based on E-FBOXEs were prepared by fast photopolymerization. can initiate photopolymerization of tripropylene glycol diacrylate under UV LED irradiation at 395 nm, final double bond conversion is achieved up 81%. Meanwhile, photocured film (PTPGDA) initiated or doped E-FBOXE-Me displays thermally reversible photochromism a moderate...
Three well-controlled biocompatible hydrophilic nanogels were synthesized, and they can effectively initiate photopolymerization improve the mechanical properties of polymers.
Abstract A 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) derivative is prepared. At first, an intermediate 4,4'‐((triazole)bis(azaneylylidene)bis(2,6‐dimethoxyphenol)) (SGA) obtained from the Schiff‐base reaction between syringaldehyde (S) and 3,5‐diamino‐1,2,4‐triazole (GA). The further product DOPO‐SGA then introduced into epoxy by blending to improve flame retardancy mechanical properties. flammability evaluation implemented limited oxygen index (LOI), UL‐94, cone calorimeter...
A novel water-soluble hyperbranched photosensitive polysiloxane urethane acrylate (WHBPSUA) was synthesized, and its structure characterized by Fourier transform infrared spectroscopy, gel permeation chromatography, 1H NMR. It found that WHBPSUA possesses good compatibility with a number of monomers deionized water.
