Additive Manufacturing of High‐Performance Polymers for Extreme Environments

Advanced Science, EarlyView.
Additive manufacturing of high‐performance polymers for extreme environments is critically reviewed through an integrated chemistry‐processing‐structure‐property‐qualification framework. The review compares fused filament fabrication, selective laser sintering, and direct ink writing, linking rheology and thermal history to crystallization, defect ...

BIOLOGICAL AND ELECTRICAL RESISTANCE OF ACETYLATED FLAX FIBRE REINFORCED POLYPROPYLENE COMPOSITES

BioResources, 2009
Flax fibre reinforced polypropylene composites were fabricated using a high speed mixer followed by injection moulding. Prior to composite production, the fibre was modified by acetylation in the presence of perchloric acid.

Interfacial Interaction‐Engineered Dual Lithiophilic Ultrathin Interlayers for Dendrite‐Suppressed Lithium Metal Textile Anodes

Advanced Science, EarlyView.
Ultrathin lithiophilic interlayers engineered on a 3D textile electrode and separator cooperatively regulate interfacial Li nucleation and Li+ transport, leading to homogeneous Li plating and mitigated dendrite formation. The resulting dual‐interfacial design provides long‐term cycling stability, improved full‐cell durability, and a scalable pathway ...

Comparative Evaluation of Compressive and Impact Strength of Cold-polymerised and Heat-polymerised Acrylic Resins Reinforced with Different Additives: An In-vitro Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Polymethyl Methacrylate (PMMA) is widely used for denture base fabrication; however, its limited mechanical properties may predispose it to fracture. Fibre reinforcement has been proposed to improve its strength and durability. Despite this,

Water‐Soluble POSS Promotes Concurrent Coalescence and Crosslinking for Multiscale‐Reinforced, Coalescent‐Free Waterborne Coatings

Advanced Science, EarlyView.
Water‐soluble amine‐functionalized polyhedral oligomeric silsesquioxane promotes concurrent latex coalescence and crosslinking, allowing epoxy‐functional particles to form continuous films without added volatile coalescing agents. The resulting multiscale‐reinforced waterborne coatings combine high strength, toughness, optical transparency, scratch ...

Hybrid fibre reinforced eco-friendly geopolymer concrete made with waste wood ash: A mechanical characterization study

Engineering and Applied Science Research, 2022
On reducing greenhouse gas emissions by the cement industry, geopolymer with an amorphous polymer form was the best alternative. Geopolymer concrete (GPC) was weak in impact strength, brittle, ductile, and energy absorption than conventional cement ...

Sea Cucumber‐Inspired Double‐Network Biopolymer Hydrogels for Programmable Soft Machines

Advanced Science, EarlyView.
Inspired by the mutable dermis of sea cucumbers, the collagen‐alginate double‐network elastomeric (CoDE) hydrogel achieves programmable, recoverable, and functional mechanical behavior. The CoDE hydrogel mimics the mutable stiffness of the sea cucumber dermis through a densified collagen cryogel scaffold that is secondarily reinforced by a dissipative,
