Valorization of silicone waste powder as industrial-waste-derived fillers in Bi2O3/EPDM nanocomposites for potential use in diagnostic X-ray protection

Thiwaporn Chumphon, Ariya Khamnuandet, Ekachai Wimolmala, Worawat Poltabtim et autres

This study valorized silicone waste powder (SWP) reclaimed from discarded silicone molds as a silica-rich secondary filler in ethylene–propylene–diene monomer (EPDM) composites containing nano-sized bismuth oxide (nano-Bi 2 O 3 ) for lead-free diagnostic X-ray shielding applications. To enhance filler–matrix compatibility, SWP …

Radiation-induced crosslinking of GO/PVDF/PEGDA composite gels: Structure, electrolyte uptake, and electrical response

Issariya Ieamviteevanich, Rattapon Khamlue, Narudee Srisawang, Pongsathorn Kumkun et autres

This work presents a radiation-induced crosslinked graphene oxide/poly(vinylidene fluoride)/polyethylene glycol diacrylate (GO/PVDF/PEGDA) composite gel matrix, combining the relatively high dielectric constant of PVDF, the flexibility of PEGDA, and the conductive properties of GO. The gels were synthesized via a green, initiator-free gamma-radiation-induced …
