DescriptionPoly(N-isopropylacrylamide) (PNIPAAm) is one of the most popular temperature responsive hydrogel which is widely used in many research fields. However, the application of PNIPAAm is significantly limited because of lack of suitable three-dimensional (3D) fabrication method. Projection Micro-StereoLithography (PμSL) is an additive manufacturing method for fabricating 3D complex micro structures. Various photo-curable resins have been processed and fabricated into 3D micro structures by PμSL. This thesis applies PμSL technique to the PNIPAAm temperature responsive hydrogel. This method can not only realize the complex three-dimensional PNIPAAm microstructures but also help reduce responsive time of PNIPAAm structures by allowing for micro scale manufacturing. Firstly, the fundamental principle of PNIPAAm temperature responsive property is investigated by temperature dependent swelling behavior experiments. Then the effects of various PμSL process parameters on temperature dependent swelling behavior are investigated to realize the control of temperature responsive property of 3D PNIPAAm structures fabricated by PμSL. Several 3D printed PNIPAAm structures are also shown. Finally, it is demonstrated that PNIPAAm-alginate double-network hydrogel enhances the mechanical property while maintaining the temperature responsive property. Sequential cross-linking method is proposed to fabricate 3D double-network hydrogel using PμSL.
