Chitosan-CNT Conductive Porous Scaffolds

Chitosan is a polyionic biopolymer that has been used as a core seaffold for constmcting porous electrode architectures. Its 3D stmcture is biocompatible and has reactive functional groups available for covalent attachment of materials or biomolecules. In addition, the scaffolds can be tailored to maximize enzyme loading. 

HIERARCHICAL MATERIALS ARCHITECTURES FOR ENZYMATIC FUEL CELLS 

One method used to modify the stracmre of chitosan to yield a porous scaffold architecture is thermally induced phase separation, which precipitates the polymer and ice crystals [79]. The ice crystals are subsequently removed under vacuum, which leaves a macroporous stracmre suitable as a scaffold for electrode construction. The porous stracmre is amenable to designs for MET and DET processes soluble mediators can freely diffuse within the macroporous matrix and the open stracmre can accommodate additional conductive nanomaterials. 

2 Polymer/Carbon Architectures Fabricated Using Solid Templates 

One specific demonstration of porogen templating by Luckarift et al. in 2012 was the incorporation of a biocompatible polymer—poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV)—into a conductive scaffold [21]. PHBV is namrally produced by bacteria and was selected for its biocompatible properties, deemed
