In-Situ Polymerization Organic-Inorganic Hybrid Materials Monomer Casting Polyamide 6/Nanorods Yttrium Hydroxide

摘要

Single crystalline Y(OH)_3 nanorods were synthesized from Y_2O_3 powder by a simple hydrothermal synthesis method under alkaline conditions. SEM images displayed that the nanorods have average diameters of about 400 nm and lengths up to several micrometers. In this paper, it is used nano-inorganic particles yttrium hydroxide to modified MC nylon. The different mass fraction of yttrium hydroxide has affected mechanical and thermal properties of the MC nylon composites. The results show that with increasing of the mass fraction of yttrium hydroxide, the impact strength is the highest value when yttrium hydroxide mass fraction of 0.25 wt%, however the tensile strength decrease 20%. And there is a little change in thermal stability when Yttrium Hydroxide added.
