Preventing nuclear fuel material adhesion on glove box components using nanoparticle coating

Abstract

Recently, studies have reported that a water-repellent coating can be created by applying nanoparticles to the surfaces of glass and polymer (Suzuki, 2007; Conti et al., 2018;Widati et al., 2019). In addition, studies suggest that a nanoparticle coating reduces, to approximately one-seventh, the adhesion force of alumina (Al2O3) particles to glass substrates, thereby providing a high adhesion-prevention effect (Suzuki et al., 2013). The nanoparticle coating also reduces the van der Waals force of adhesion due to the formation of nanoscale asperities on the surfaces of substrates and particles (Suzuki et al., 2013;Yang et al., 2005; Deng et al., 2017). The nanoparticles aggregating on the acrylic surface are smaller than the wavelength of visible light, and hence the transparency of the acrylic panel remains undiminished with the use of coatings
