Permeation Properties of Polymer/Clay Nanocomposites
The important characteristics of polymer/clay nanocomposites are stability, barrier properties and in the case of polyvinyl chloride also plasticizer migration into other materials. Therefore, the permeation properties of polymer/clay nanocomposites are discussed in this paper. The attention was focused to the polyethylene (PE) and polyvinyl chloride (PVC). Natural type of montmorillonite MMTNa...
متن کاملCo2-mediated Formation of Polymer/clay Nanocomposites
QIAN ZHAO: CO2-mediated formation of polymer/clay nanocomposites (Under the direction of Edward T. Samulski) In this thesis, the feasibility of scCO2 as both a processing medium and a polymerization medium for preparation of polymer/clay nanocomposites has been explored, with the first part discussing a CO2-mediated intercalation of poly(ethylene oxide) (PEO) in clay. It has been shown that CO2...
متن کاملLight induced curing of Clay/Polymer nanocomposites
Clay nanocomposites have been synthesized by UV-curing with organic and waterbased resins. The effect of the chemical structure of the organophilic layer of the clay on the dispersibility in the photocurable resins, the photocuring efficiency and the final properties of the UV-cured nanocomposites are discussed.
متن کاملInfluence of Polymer-Clay Interfacial Interactions on the Ignition Time of Polymer/Clay Nanocomposites
Metal ions present on smectite clay (montmorillonite) platelets have preferential reactivity towards peroxy/alkoxy groups during polyamide 6 (PA6) thermal decomposition. This changes the decomposition pathway and negatively affects the ignition response of PA6. To restrict these interfacial interactions, high-temperature-resistant polymers such as polyetherimide (PEI) and polyimide (PI) were us...
متن کاملConducting, Self-Assembled, Nacre-Mimetic Polymer/Clay Nanocomposites.
UNLABELLED We demonstrate electrically and ionically conducting nacre-mimetic nanocomposites prepared using self-assembly of synthetic nanoclay in combination with PEDOT PSS and a poly(ionic liquid) polymer from aqueous dispersions. The resulting nacre-mimetics show high degrees of mesoscale order and combine high stiffness and high strength. In terms of conductivities, the resulting hybrids ...
