Conductive, Gas Barrier, and Thermal Resistant Behavior of Poly (methyl methacrylate) Composite by Dispersion of ZrO₂Nanoparticles

Abstract

Poly (methyl methacrylate)=zirconium dioxide (PMMA=ZrO 2 ) nanocomposites were prepared by the incorporation of ZrO 2 nanoparticles in various proportions (2, 4, 6, 8, and 10%) with PMMA matrix by in situ emulsifier-free emulsion polymerization technique. The structural property of PMMA=ZrO 2 nanocomposites was studied by X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. The thermal stability of PMMA=ZrO 2 nanocomposites was improved with increasing concentration of ZrO 2 . The electrical conductivity of composites was measured as function of ZrO 2 concentration. The oxygen barrier properties of PMMA=ZrO 2 nanocomposites were measured by using gas permeameter.

Electrospun Polyvinyl Borate/Poly(Methyl Methacrylate) (PVB/PMMA) Blend Nanofibers

“…The scission at the vinyl terminated end and to random scission of the PMMA backbone, respectively. The degradation profile of pure PMMA is in agreement with the literature [33][34][35][36]. PVB has a pronounced effect on the thermal behavior of PVB/PMMA blend degradation.…”

Graphite‐reinforced oxygen barrier conducting starch bionanocomposites

“…. This is also supported by the dispersion of EG in the starch matrix as shown in FESEM image which enables to form a connecting network for better electrical conductivity .…”

“…Stabilność badanych układów na działanie promieniowania ultrafioletowego (tab. 6), nawet opartych na żywicach ketonowych i mastyksowych, które są bardzo podatne na żółknięcie, jest prosta do wyjaśnienia i opiera się na działaniu pigmentów bieli zawartych w farbach jako substancji ekranujących 25 oraz na efekcie barierowym 26 .…”
