Who Lives in a Tin Can Under the (Ultrasonic) Sea: Sponges Made From Perfluoropyridine‐Derived Thiol‐Ene Polymerizations

open access: yesJournal of Polymer Science, EarlyView.
Tandem mechanochemical‐sonochemical for the strategic synthesis for 2,4,6‐trisubstituted derivatives of perfluoropyridine as bio‐based prepolymer materials. ABSTRACT Substitution of perfluoropyridine (PFP) in the 4‐position through an SNAr reaction is facile through mechanochemical methods, with yields in excess of 99% and short reaction times on a ...

Comparison of the Coating Structure of Silicon‐Based PECVD Coatings With Varying Organic Content

open access: yesPlasma Processes and Polymers, EarlyView.
Silicon‐based PECVD coatings transition abruptly from organic SiOCH to oxidic SiOx at ~32 at% silicon, exhibiting threshold behavior in barrier performance. Chemical composition seems to dominate over porosity: SiOx coatings unexpectedly show higher porosity yet superior barrier properties, possibly due to rigid cage‐like molecular structures ...

Assessment of the Interaction between Ammonium Dinitramide and Isocyanurate Bonding Agents for Application on Technologies of Composite Solid Propellants

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
This work investigates the interaction of two isocyanurate‐based bonding agents with ammonium dinitramide: triallyl isocyanurate and 1,3,5‐tris(2‐hydroxyethyl) isocyanurate, which contain alkene and hydroxyl functional groups in their side chains, respectively.
