Besides conducting polymers, these nanocomposites will be composed of some carbon nanomaterials, such as carbon nanotubes and graphene, to promote the conductivity and mechanical properties. The hydrogels will be fabricated by using photo-curing. That allows us to make a 3D scaffold simply by integrating 3D printer with a UV light source. In the second year of this project, the focus is the integration of a 3D printer with a UV light to develop the system for making conducting hydrogels. The shape of hydrogels can be easily designed through a CAD software. We will evaluate the electrochemical properties and conductivities of the hydrogels. We will also use atomic force microscope to observe the microstructure of the hydrogels. That allows us to correlate their properties and structures. Then, we will test the biocompatibility of this conducting hydrogels. We will further evaluate the feasibility to promote the cell growth on these hydrogels through electrical stimuli.導電水凝膠3D列印支架奈米複合材料功能性導電高分子conducting hydrogels3D printingscaffoldnanocompositefunctionalized conducting polymers
