Polymer-ceramic nanocomposite membranes

Novel polymer-ceramic nanocomposite membranes were fabricated, characterized, and tested for their barrier performance. Atomic layer deposition (ALD) was used to deposit alumina films on primary, micron-sized (16 and 60 pm) high-density polyethylene (HOPE) particles at a rate of 0.5 nm/cyde at 77 °C. Well-dispersed polymer-ceramic nanocomposites were obtained by extruding aluminapolymer particle size. The diffusion coefficient of fabricated nanocomposite membranes can be reduced to half with the inclusion of 7.29vol.% alumina flakes. However, a corresponding increase in permeability was also observed due to the voids formed at or near the interface of the polymer and alumina flakes during the extrusion process, as evidenced by electron microscopy [1].
