Functionalized multilayer thin films for protection against acutely toxic agents

[摘要] (cont.) Finally, the Spray-LbL technique is used to asymmetrically functionalize electrospun materials with multiple coatings. By simply varying the flow rate of charged species passing through an electrospun material during Spray-LbL deposition, individual fibers within the matrix can be conformally functionalized for ultra-high surface area catalysis, or bridged to form a networked sublayer with complimentary properties. Exemplified here by the creation of selectively-reactive gas purification membranes, the myriad applications of this technology also include self-cleaning fabrics, water purification, and protein functionalization of scaffolds for tissue engineering.
