Abstract

To resolve the problems of traditional lead-based substrates

such as low shielding efficiency in the energy range of 40-88 keV

biological toxicity

and the deterioration of mechanical properties caused by filler agglomeration in epoxy matrix

we put forward a "core-shell structure optimization-surface chemical bonding" strategy to fabricate gadolinium-bismuth-epoxy composite shielding coatings. Using gadolinium oxide and bismuth oxide as the cores

Bi@Si/Gd@Si core-shell nanoparticles were synthesized. Subsequently

the amino groups were introduced onto the surface of the nano

particles through KH550 modification. Finally

these nanoparticles were compounded with epoxy resin. After ultrasonic dispersion and a heat curing process

the gadolinium-bismuth-epoxy composite shielding coatings were successfully fabricated. Both the thermal stability and mechanical properties of the composite coatings were enhanced by incorporation of fillers. The bonding strength of the composite coatings (with 50% filler loading) reached 25.80 MPa. The X-ray shielding efficiency of the coatings for

129

I source was 93.8%. The theoretical thickness required to half shielding of the intensity of

-rays from

137

Cs source was 3.63 cm. This coating combined high bonding strength and excellent shielding efficiency could be applied to the equipment

via

spraying or other techniques

thus presenting broad application prospects in fields such as nuclear power plants and space station protection.
