Polymers are an integral component of modern life, permeating the food and health industries and enhancing consumer safety, wellness, and convenience. With the increasing amount of polymers being used, their waste materials are reaching a significant level, leading to ever-increasing contaminations in the waterways, wildlife, and human bodies. Synthetic polymers are divided into two basic categories: thermoplastics that can be easily recycled due to their un-crosslinked networks, and thermosets with permanently crosslinked networks that are difficult to reprocessed using conventional techniques. Recently, dynamic covalent chemistry has been employed to develop the covalent adaptable network (CAN) polymers, which enable thermosets to be malleable, self-healable, and fully recyclable. When combined with the emerging advanced manufacturing techniques, CANs can not only enhance the manufacturing capabilities and material properties of polymers and their composites but also help reduce the polymer wastes to enable green and sustainable manufacturing processes. This thesis focuses on the healing and recycling capabilities of thermosetting polymers based on CANs, as well as their integration with polymer manufacturing processes to reduce wastes, enhance material properties, and enable new manufacturing techniques. First, the surface welding behavior of CANs is studied to understand how the processing temperature, time, and surface roughness will affect the welding strength. The recyclability of engineering thermosets using organic solvents is then studied, and the influences of material and processing conditions on the recycling speed and properties of recycled materials are investigated. Using the direct ink write (DIW) 3D printing method, the solvent-assisted recycling of CANs is shown to effectively enable the recyclable 3D printing of thermosets and their conductive composites for electronics applications. It also enables new manufacturing methods for thermoset composites with continuous carbon fiber. Overall, the application of CANs shows great potential to enable sustainable manufacturing and recycling methods of thermosets and their composites for a future sustainable society.
