The Effect of Single Curing Agents on the Curing Reactions of the HTPB-based Binder System
Coatings, 2022 As the hydroxyl-terminated polybutadiene (HTPB)-based binder system is widely applied in many industries, the curing process plays an important role in the final properties of the resulting product containing such a binder system.

Burning Properties of Uncured HTPB Propellant
Journal of the Korean Society of Propulsion Engineers, 2016 ABSTRACT In this study, we examined the burning rate of the uncured pr opellant (with and without a curing agent application) in order to inspect the process of the HTPB solid propellant. The burning rate of the uncured propellant, that did not contain the curing agent, was approximately 9.7 mm/s at 1000 psi. In relation to the curing time, the burning

Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT The objective of this paper is to demonstrate the advantage of computationally pre‐screening surface‐modifying material candidates, using density functional theory (DFT), to inform experimental synthesis and formulation efforts. This demonstration focuses on improving the solubility of benzene‐based materials in hydroxyl‐terminated ...

Smart Molecules, EarlyView.This study addresses stability, repair, and recycling in flexible devices using polymers with identical dynamic bonds but incompatible backbones. This enables robust integration, precise self‐healing, and full recyclability. We demonstrate optoelectronic sensors that, after damage, magnetically self‐assemble and heal upon heating.
