The monoacylphosphineoxide (MAPO) salts Na-TPO and Li-TPO the bisacylphosphineoxide (BAPO) BAPO-ONa BAPO-OLi define an important in latter case a new class of water-soluble photoinitiators (PIs) for radical polymerization. These compounds showed excellent water-solubility at least 29 g/L up to 60 deionized water, thus exceeding solubility state art PI water-based systems Irgacure 2959 (I2959) 6- 12-fold. However, biocompatibility, storage stability, reactivity were equally replace compounds....
Cellulose nanocrystals (CNCs) with >2000 photoactive groups on each can act as highly efficient initiators for radical polymerizations, cross-linkers, well covalently embedded nanofillers nanocomposite hydrogels. This is achieved by a simple and reliable method surface modification of CNCs bis(acyl)phosphane oxide derivative. Shape-persistent free-standing 3D structured objects were printed mono-functional methacrylate, showing superior swelling capacity improved mechanical properties.
A bis(acyl)phosphane oxide (BAPO) photoinitiator was conveniently synthesized in an efficient one-pot process. It shows excellent dispersibility water, good storage stability, and high photo-reactivity 3D printing of hydrogels under visible-light irradiation (460 nm).
Vat photopolymerization 3D printing provides new opportunities for the fabrication of tissue scaffolds and medical devices. However, manufacturing biodegradable elastomers, it usually requires use organic solvents to dissolve solid photoinitators achieve low resin viscosity, making this process environmentally unfriendly not optimal biomedical applications. Here, we report solvent-free elastomers by digital light processing with well-defined photoinitiator–polymer conjugates. Being in liquid...
A new bis(acyl)phosphane oxide photoinitiator was immobilized on surfaces of cellulose nanocrystals and used for polymer grafting.
Because of their complex supermolecular structure, coal structures are challenging. We have tried to establish a novel method construct three-dimensional chemical model with proper reactivity for Yuzhou lignite using experimental and theoretical methods. Structural units the were built elemental analysis, infrared 13C nuclear magnetic resonance spectra, density functional theory calculation. A was in periodic box order rationalize intra- intermolecular interactions. To confirm validity...
Additive manufacturing (AM) methods are being integrated in ceramics fabrication either as the main tool or for auxiliary purposes. By using polymers, powders and preceramic formulated materials, AM techniques pushing towards higher resolution, lower shrinkage shorter building time. Herein, we present of ceramic microstructures (< 200 × μm3) with sub-micrometer resolution based on two-photon polymerization (TPP). 3D structuring a resin by photopolymerization produces so-called green body....
Polypyrrole/NiFe-layered double hydroxide composite with excellent microwave absorption capability and anti-corrosion performance that can be used in marine environments.
The synthesis of N-CF3 compounds through fluorination or trifluoromethylation N-containing has been extensively investigated. However, general access to simply from secondary amines is hampered by the challenging preparation and instability these amines, as well a much lower reactivity due strong electron-withdrawing nature steric bulk trifluoromethyl moiety. Herein, we report highly efficient with excellent isolated yields via addition in situ generated difluoromethyl imine (R-N=CF2 )...
Abstract Additive manufacturing (AM) of copper through laser‐based processes poses challenges, primarily attributed to the high thermal conductivity and low laser absorptivity powder or wire as feedstock. Although use salts in vat photopolymerization‐based AM techniques has garnered recent attention, achieving micro‐architected with density remained elusive. In this study, we present a facile efficient process create complex 3D structures superior electrical hardness. The entails formulation...
Flexible ultra-compact low-loss optical waveguides play a vital role in the development of soft photonics. The search for suitable materials and innovative fabrication techniques to achieve low loss long polymer interconnects has proven be challenging. In this paper, we demonstrate submicron polydimethylsiloxane (PDMS) using divinylbenzene (DVB) as photopolymerizable monomer through two-photon polymerization (2PP). We show that commercial oxime ester photoinitiator Irgacure OXE02 is...
Polythioamide is a unique type of sulfur-containing polymer with advanced functionalities. Nonetheless, the elemental sulfur commonly used in their synthesis tends to react readily unsaturated functional groups, thereby limiting scope eligible substrates. Inspired by highly efficient sulfur-fluoride exchange (SuFEx) polymerization through discrete hubs, we present herein pioneering and versatile approach polythioamides from diboronic acids, secondary diamines, thiocarbonyl fluoride as...
A multifunctional photoinitiator is presented, offering precise control over light-induced polymerization initiation at 450 nm and material degradation 365 nm. This accomplished by covalently linking photoactive bis(acyl)phosphane oxide photocleavable o-nitrobenzyl ether moieties onto the surface of γ-cyclodextrin. Upon degradation, resulting linear polymers can be easily re-dissolved in their corresponding monomer re-cured, exhibiting superior mechanical properties compared to pristine...
