Recent Advances and Prospects in High‐Performance Bio‐Based Phthalonitrile Resins

open access: yesAdvanced Functional Materials, Volume 34, Issue 51, December 16, 2024.
Partially bio‐based phthalonitrile resins, originally developed as heat‐resistant materials like their fossil‐based counterparts, can be explored for broader applications due to their attractive performance characteristics. While challenges remain, particularly in processability and thermal performance, recent advancements in molecular design and green

Microfabrication Technologies for Nanoinvasive and High‐Resolution Magnetic Neuromodulation

open access: yesAdvanced Science, Volume 11, Issue 46, December 11, 2024.
Advancing neuromodulation requires enhanced stimulation resolution. Magnetic stimulation, known for minimal signal loss and tissue damage, is pivotal but current methods like transcranial magnetic stimulation lack precise targeting. Future technologies must achieve submillimeter resolution and selective neuron modulation.

Investigating the changing dynamics of processing, temperature‐based mechanics, and flame retardancy in the transfer of ammonium polyphosphate/inorganic silicate flame retardants from epoxy resins to glass fiber composites

open access: yesJournal of Applied Polymer Science, Volume 141, Issue 39, October 15, 2024.
This study examines the dynamics of varying the combined content of ammonium polyphosphate and inorganic silicate in epoxy resins on processibility and fire performance upon transfer to glass fiber reinforced composites. A 30% loading of the flame retardants was crucial for the recovery of the UL‐94 V‐0 rating and charring action absent in a 10 ...

Carbon‐based Flame Retardants for Polymers: A Bottom‐up Review

open access: yesAdvanced Materials, Volume 36, Issue 42, October 17, 2024.
Is it really understood how flame retardants work at the molecular level? The use of cutting‐edge simulations via molecular dynamics sets a precedence for an alternative bottom‐up approach to better comprehend the thermal resisting process of carbon‐based flame retardants, such as the char formation and radical capturing offered by the unique carbon ...

Reactivity, processability, and thermal stability of tetrafunctional glycidyl ether cyclic siloxane epoxy hybrid networks

open access: yesJournal of Applied Polymer Science, Volume 141, Issue 33, September 5, 2024.
Cyclic siloxane epoxy resins cured with aromatic amines are highly processable yet durable at elevated temperature. Abstract A low viscosity tetra‐functional cyclosiloxane epoxy resins (TGTS) is synthesized via a one‐step hydrosilylation reaction and cured separately with four different aromatic diamines to explore the reaction kinetics, network ...

SYNTHESIS AND CHARACTERISATION OF BISPHENOL A NOVOLAC EPOXY RESINS FOR COATING APPLICATIONS [PDF]

open access: yesAl-Azhar Bulletin of Science, 2008
Bisphenol A novolacs were synthesized in a melting process using para formaldehyde, and in a solution process using formalin solution and oxalic acid catalyst. 1H-NMR investigations show a higher content of methylene bridges in the novolacs synthesized by the melting process. These novolacs were analyzed by GPC and FT-IR spectroscopy.
