Nickel alginate‐enhanced fire safety of aluminum diethylphosphinate on epoxy resin

Journal of Applied Polymer Science, Journal Year: 2022, Volume and Issue: 140(9)

Published: Dec. 24, 2022

Abstract To attain superior fire safety epoxy resins (EP), aluminum diethylphosphonate (AlPi) and nickel alginate were incorporated to EP in different proportions. The synergistic flame retardant effects between AlPi on mechanical properties of investigated detail. EP/AlPi 9.5 ‐Nickel Alginate 0.5 acquired the UL‐94 V‐0 rating with highest limiting oxygen index value (28.9%). Besides, thermal decomposition behaviors samples researched by thermogravimetric analysis, implying that EP/AlPi‐Nickel exhibited better stability char‐forming ability. Compared EP, peak heat release rate total declined 58.3% 12.8%. And addition reduced smoke. In particular, incorporation increased impact strength, flexural strength glass transition temperature EP. perspective, effect bio‐based opens a practicable avenue decreasing risk improving

Multielement Flame-Retardant System Constructed with Metal POSS–Organic Frameworks for Epoxy Resin

ACS Applied Materials & Interfaces, Journal Year: 2022, Volume and Issue: 14(43), P. 49326 - 49337

The direct coordination between polyhedral oligomeric silsesquioxane (POSS) and Co forms an assembly of nanoparticles with low specific surface area leads to a poor dispersion state in the epoxy resin matrix, resulting unsatisfactory flame-retardant efficiency. Metal-organic frameworks (MOFs), for instance, ZIF-67, provide not only cobalt element but also porous framework that endows nanocomposite MOFs POSS high abundant sites silica skeleton. Herein, ZIF-67 is hybridized octacarboxyl POSS, removal alkaline ligand form novel metal POSS-organic (MPOFs). size differences organic groups nanocages vs. micropores gave rise reverse click reaction, reforming octavinyl isolated on outer complex, which could be further modified by phosphorous flame retardant using addition reaction. obtained MPOFs-P 2 wt % loading improve limiting oxygen index value composites 27.0% pass V-0 rating UL-94 test. Meanwhile, peaks heat release rate especially total smoke production were reduced 46.6 25.2%, respectively. robust char layer reduces emission toxic gas CO 39.8%. above product promising retardancy improved mechanical properties, thanks filler unique nanostructure. ingenious work offers enlightenment hybridization method fabricate multielement system efficacy.

An Individualized Core–Shell Architecture Derived from Covalent Triazine Frameworks: Toward Enhancing the Flame Retardancy, Smoke Release Suppression, and Toughness of Bismaleimide Resin

ACS Materials Letters, Journal Year: 2023, Volume and Issue: 5(2), P. 630 - 637

Published: Jan. 26, 2023

Although the bismaleimide (BMI) resin is a star material in industries, its further applications have been plagued by serious brittleness and fire hazard for long time. Hence, core–shell architecture (MPPM) derived from covalent triazine frameworks was designed to overcome shortcomings. Excitedly, compared those of neat BMI, resultant BMI-2 with only 1 wt % MPPM capable achieving 23.4%, 48.6%, 39.7% decrements on peak heat release rate, total release, smoke respectively, exhibiting unprecedented flame-retardant effects under low addition flame retardants. Besides, impact strength enhanced 62.7% close tensile storage modulus implying that toughness BMI improved successfully without sacrificing rigidity. This work provided unique clue designing efficient multifunctional modifiers promoted development advanced BMI.
