Dual-curable stereolithography resins for superior thermomechanical properties

eXPRESS Polymer Letters, 2020
Stereolithography (SL) stands out as a relatively fast additive manufacturing method to produce thermoset components with high resolutions. The majority of SL resins consist of acrylate monomers which result in materials with curing-induced shrinkage ...

Liquid Crystal Elastomer‐Based Haptic Pixel Arrays at Your Fingertips for Advanced Human–Machine Interfaces

Advanced Materials, EarlyView.
We mechanically program liquid crystal elastomer coatings as a stimuli‐responsive and digitally addressable platform for refreshable tactile displays; we validate the perceptual performance of our dynamic device matches conventional static tactile media.

Soft Yet Tough Tanglemers Through Rapid Photopolymerization for DLP 3D Printing

Advanced Materials, EarlyView.
Soft yet tough tanglemers are produced through low‐initiator free radical photopolymerization and translated to DLP 3D printing. Systematic control over light intensity, initiator loading, and crosslink density reveals processing windows that balance printability, elasticity, toughness, and feature fidelity. ABSTRACT Additive manufacturing of compliant

Direct synthesis of ultrahigh molecular weight ethylene/acrylate copolymers catalyzed by binuclear Ni catalytic system

Giant
The non-polar nature of ultrahigh molecular weight polyethylene (UHMWPE) inherently limits its high-end applications. Introducing polar functional groups into the polyethylene (PE) chain can enhance its surface and rheological properties, further ...

Novel (meth)acrylate monomers for ultrarapid polymerization and enhanced polymer properties [PDF]

, 2002
Ultraviolet light is known to be one of the most efficient methods to initiatc polymeric reactions in the presence of a photonitiator. Photopolymerizations are advantageous because the chemistry of the materials can be tailored to design liquid monomers ...

Evaluation of a Potential Ionic Contribution to the Polymerization of Highly Reactive (Meth)acrylate Monomers

, 2016
Monovinyl methacrylic and acrylic monomers that exhibit enhanced photopolymerization reactivities were studied to discern a possible secondary polymerization mechanism that involves an anionic contribution to the polymerization. To test for this possible

Metastable Polymers for Circular 3D Printing

Advanced Materials, EarlyView.
3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Preparation and characterization of interpenetrating networks based on polyacrylates and poly(lactic acid)

eXPRESS Polymer Letters, 2012
Three different, multifunctional acrylic monomers were photopolymerized in a matrix of poly(lactic acid), PLA, using 2-hydroxy-2-methyl-1-phenyl-propan-1-one as a photoinitiator.

Fast Hydrogel Micro‐Actuators Driven by Electric Fields

Advanced Materials, EarlyView.
We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...
