Advanced Flame-Retardant Methods for Polymeric Materials

Bo-Wen Liu et al.

Summary: Most organic polymeric materials are highly flammable, causing significant damages to human life and property through the large amounts of smoke, toxic gases, heat, and melt drips produced during burning. Conventional flame-retardant methods are facing difficulties in meeting the increasing flame-retardant requirements. Advanced flame-retardant methods, such as all-in-one intumescence and nanotechnology, have been developed to provide potential solutions to these challenges.

Poly(acrylic acid)-Based Hydrogel Actuators Fabricated via Digital Light Projection Additive Manufacturing

Yuyang Wang et al.

Summary: This study investigates the fabrication of cross-linked poly(acrylic acid)-based actuators using digital light projection (DLP), which enables the production of actuators with complex geometries. The 3D-printed actuators exhibit large deformation, high actuation speed, and stable performance under relatively low actuation voltage. Factors such as acrylic acid content, cross-linker concentration, actuator thicknesses, and electric field strength were varied and evaluated.

Polyelectrolyte photopolymer complexes for flame retardant wood

Thomas J. Kolibaba et al.

Summary: A new photopolymerized flame retardant coating has been developed by forming a polyelectrolyte complex from an anionic phosphate-containing methacrylate and cationic polyethylenimine. This coating not only enhances the mechanical strength of plywood at high temperatures, but also reduces the heat release rate and smoke release, making wood structures safer.

4D printing materials for vat photopolymerization

Alberto Andreu et al.

Summary: Vat photopolymerization is a highly accurate and accessible additive manufacturing process, with recent developments leading to 4D printing where objects transform into predefined structures with external stimuli. Research shows that acrylate-based resins are widely used for 4D printing, with DLP being the most adopted technology due to grayscale lithography capabilities. Further development of new materials and faster progress are needed for wider adoption of this technology in industry.
