Short Description
Vacuum-assisted self assembly for inexpensive, fast production of nanocomposites
Abstract
Northwestern researchers have developed an improved method for producing nanocomposites. While composites produced by layer-by-layer (LBL) assembly, a common methodology, have excellent mechanical properties, LBL has a number of drawbacks, including limited material selection, setup cost and complexity, fabrication speed, and a narrow range of interlayer polymer composition. This new technology called vacuum-assisted (VASA) is a highly flexible technique for fabricating well-ordered, free-standing graphene oxide-polymer nanocomposite films/papers with high nanofiller concentrations (>50 wt%). It uses a simple, inexpensive membrane filter to obtain material with significant proportions of both polymer and nanofiller components from a colloidal solution of graphene oxide and polymer. VASA rapidly produces macroscopic samples of homogenous layered graphene oxide-polymer nanocomposities with either hydrophilic or hydrophobic polymers. Because VASA relies on filtration for assembly instead of alternating layer deposition, it is a complimentary method to LBL for fabricating layered polymer nanocomposites, expanding the scope of these layered materials with the following advantages: wider material selection, inexpensive and simple setup, faster buildup of layers, and wide range of intergallery polymer content.
Applications
o Gas separation membranes
o High-strength structural materials
Advantages
o Highly flexible technique
o Rapid production
o Inexpensive and simple setup
o Wider material selection
o Faster buildup of layers
o Wide range of intergallery polymer content
