Abstract

Two lanthanum hydroxide (LH, La(OH)₃) materials, i.e., La(OH)₃ submicroplates (LHSMPs) and La(OH)₃ nanoparticles (LHNPs), were synthesized hydrothermally, and their optical and encapsulation properties were investigated. The surfaces of the LHSMPs and the LHNPs were modified with a coupling agent: [3-(methacryloyloxy)propyl] trimethoxysilane (MPS). To prepare transparent encapsulation composite materials, both types of surface-modified particles were dispersed in a poly(urethane acrylate) (PUA) adhesive polymer binder. The composite film with surface-modified LHNP-PUA exhibited better optical properties (higher transmittance and lower haze) than that with surface-modified LHSMP-PUA owing to smaller particle size. However, the latter was observed to be more advantageous for preventing the permeation of water molecules owing to the larger particle size.
