Structure–Reactivity Relationships of Oxime–Oxalate/Glyoxylate/Ester Derivatives: Dual Photo/Thermal Initiators for Visible Light Polymerization and Composite Preparation [PDF]
Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.OP1, a newly synthesized nitro‐carbazole oxime oxalate, shows superior Type I photoinitiation under blue LEDs and sunlight due to efficient decarboxylation. It enables high‐resolution 3D printing, offers dual photo/thermal initiation, lower cytotoxicity than TPO, and provides insights for designing sustainable photoinitiators.

Polymer Testing, 2020 Abstract The frictional behaviors of prepreg-prepreg and prepreg-tool play the most important role in hot diaphragm forming and greatly influence the quality of the final product. A new set-up was developed to characterize the frictional behaviors for unidirectional carbon fiber/epoxy prepreg.
