Electrodeposition Assisted Dynamic Assemblies of Chitosan/Alginate Composite Multi-Membrane

AbstractElectrodeposition of natural polymer as aneffective approach to improve bioactivity ofthe conductive substrate has receives much attentions in medical and otherapplications. In this work, we developed a novel chitosan/alginate (CS/ALG)multi-membrane on titanium plate via the electrodeposition assisted dynamicassembly approach. Specifically, the electrical signal induced CS coating can serve as a versatileplatform for layer by layer assemblies of ALG into the   multi-membrane through   strong electrostatic   interaction. The   prepared multi-membranes exhibit greatswelling performance and excellent mechanical properties at dried states, with the tensile stress and strain valuesreaching to 58.2 MPa and 4.25 % for the 10 layers sample. In summary, webelieve such green, low cost and rapid fabrication approach and mild processingenvironment would spur great potential for construction of multi-functionalcoating and smart drug elution system on the conductive implants.
