Preparation of Ruthenium-Containing Polycarbonate Films and the Chemistry of Ruthenium in Polycarbonate

Abstract

RuCl3·3H2O complexes have been incorporated into polycarbonate using solvent. The interactions between Ru complexes and polycarbonate (PC) are examined by infrared spectroscopy and thermal analysis. The reaction chemistries of these Ru-containing films have been investigated by reacting the Ru sites with CO, O2, H2, D2, NO, and C2H4. They show interesting catalytic activities in various gas phase reactions under relatively mild conditions such as NO reduction, hydrogenation of ethylene and benzene, water-gas shift reaction, and oxidation of n-butyl sulfide.

Preparation and electrochemical studies of layered PANI/HNb3O8 nanocomposite

“…Similar results were also revealed in the polymerization of AnHNb initiated by chemical oxidant FeCl 3 or microwave irradiation†, but the net interlayer heights of nanocomposites PANIHNb‐Fe 3+ and PANIHNb‐MW are 4.4 and 7.4 Å, respectively. These expansions are also corresponding to the formation of a single‐layer arrangement of PANI molecules (Scheme , right) and comparable with the published values of ∼ 4.2 Å in PANI/UO 2 PO 4 and PANI/MnPS 3 , and ∼ 7.0 Å in PANI/V 2 O 5 , PANI/MoO 3 , and PANI/FeOCl, etc 11–17…”

“…MacDiarmid and coworkers once studied the microcrystalline form of PANI and proposed a crystal structure 8. To obtain oriented polymer chains, the polymer molecules were forced to grow inside the structurally organized three‐dimensional hosts with large oriented tunnels and two‐dimensional ones with an interlayer space 10–17. Recently, Petkov et al10 studied the three‐dimensional structure of PANI/V 2 O 5 nanocomposite by using the technique of atomic pair distribution function.…”

Nanocomposites of Polyaniline and a Layered Inorganic Acid Host: Polymerization of Aniline in the Layers, Conformation, and Electrochemical Studies

“…[10] To obtain oriented polymer chains, the polymer molecules could be grown inside the structurally organized hosts such as 3D hosts with large oriented tunnels and 2D hosts with interlayer space. Recently, it has been reported that PANI could be inserted in layered materials such as V 2 O 5 , [11] MoO 3 , [12] phosphates, [13] chlorides, [14] oxychlorides, [15] and clays, [16] and mesoporous host MCM-41. [17] By inserting the monomer aniline into layered materials followed by polymerization between the layers using different methods, two dissimilar chemical components can be hybridized at a molecular level.…”
