Dry　photopolymer　materials　are　being　actively　studied　for　practical　applications　such　as　holographic　data　storage,　3D　display,　wearable　displays　with　diffractive　optical　elements　and　so　on.　Their　versatility,　ease　of　use　and　self-processing　ability　give　them　many　advantages　over　more　traditional　recording　materials　such　as　silver　halide　and　dichromate　gelatin　for　holographic　uses.　The　necessity　for　development　and　optimization　of　such　dry　photopolymer　diffraction　elements　with　higher　capability　and　stability　has　been　recognized　and　they　have　recently　received　significant　attention　in　the　areas　of　holographic　and　wearable　displays.　In　this　work,　we　carried　out　nanoparticles　composites,　which　are　based　on　a　SiO2　nanoparticle　doped　acrylate-thiol-ene　photopolymer　material,　in　order　to　fabricate　holographic　diffraction　elements　for　3D　display　uses.　Preliminary　examination　on　this　material　and　fabrication　techniques　shows　that　a　flexible　free-standing　volume　grating　with　thickness　of　200　mu　m　and　grating　period　of　1　mu　m　was　fabricated　by　using　proposed　nanoparticle　composite　material　in　the　recording　wavelength　of　532　nm.　The　examination　on　thinner　material　layers　with　varied　nanoparticles,　such　as　in　the　range　of　10　mu　m,　is　undergoing.　We　believe　that　such　holographic　diffraction　elements　offer　a　significant　potential　in　display　technique.
