Preparation and characterization of poly(methyl methacrylate)‐intercalated graphite oxide/poly(methyl methacrylate) nanocomposite

Abstract

A poly(methyl methacrylate)‐intercalated graphite oxide/poly(methyl methacrylate) nanocomposite was prepared by emulsion polymerization of methyl methacrylate in the presence of graphite oxide (GO). GO was synthesized by the oxidization of natural graphite powder with KMnO4 in concentrated sulfuric acid. The functional groups and microstructure of the oxidized graphite and the composite were carefully characterized by use of X‐ray diffraction, infrared, transmission electron microscopy, and elemental analysis. The electrical conductivity and mechanical properties were also measured. Polym. Eng. Sci. 44:2335–2339, 2004. © 2004 Society of Plastics Engineers.

Compatibilizing effect of graphite oxide in graphene/PMMA nanocomposites

“…GO used as a compatibilizer (GO-1) was prepared by oxidizing graphite with KMnO 4 /H 2 SO 4 . 15,17,18 Elemental analysis showed that the GO composition was C 10 O 2.28 H 1.31 . The conductivity was 0.5 S/cm.…”

Fabrication and characterization of poly(methyl methacrylate)/CaCu3 Ti4 O12 composites

“…The Poly(Methyl Methacrylate) (PMMA), a transparent thermoplastic polymer, possesses moderate physical properties associated with low cost and composite systems based on this were studied in great detail . It is reported that, for the PMMA+Al 2 O 3 composite system, Al 2 O 3 loading to the level of 45 vol%, increased the permittivity and has been attributed to the space charge polarization mechanism .…”

Effect of graphite oxide on photodegradation behavior of poly(vinyl alcohol)/graphite oxide composite hydrogels

“…GO has intercalated or exfoliated structures in the polymer matrix that create a nanocomposite similar to montmorillonite [17,18]. In addition, GO can impart an electric conductivity to the polymer composites [19] and can be used as a host material for the synthesis of conducting polymer intercalated nanocomposites [20,21].…”
