Multilayers inorganic-organic

Organic molecules such as aniline, pyrrole and 2,2 -bithiophene have been intercalated and polymerized within the galleries of clay minerals, FeOCl, V2O5 gel and other layered hosts to yield multilayered inorganic/organic polymer nanocomposites...

To fabricate different polymer layers in a device using solution based techniques, mutually exclusive solvents have to be identified, which is often very difficult. CVD eliminates these difficulties and excellent heterojunctions and multilayered films can be fabricated relatively easily. Also, the capability to co-deposit compounds can be achieved. This ease of co-depositing compounds has enabled the synthesis of several inorganic-organic hybrids, which can also be tailored as nanocomposites at the molecular level. 

Chapter 9 demonstrates how membrane modification based on the incorporation of inorganic/organic particles and multilayer membranes has a promising future in pervaporation (PV). This separation process continues to emerge as a feasible separation technology for many different and diverse applications from purification of solvents to wastewater treatment. As a proven method of separation at low temperatures and pressures, further development and modification of membranes are likely to be undertaken to improve PV application in food processing. In addition, the modification of PV membranes to improve the removal of a variety of organic compounds to clean wastewater streams also holds much promise. 

Inorganic-organic polymers already exhibit good barriers on polymeric substrates. However, in combination with an inorganic barrier layer their barrier properties are improved not only by the coating thickness, but also through the interaction with the MeO layer. These synergistic effects can be illustrated for different multilayer structures by three theoretical models (see Fig. 21-22(a)-(c)).
