Abstract
The purpose of the proposed project is twofold: (i) to develop and establish a recycling protocol for two antimicrobial polymers used in additive manufacturing, and (ii) to assess mechanical characteristics of the recycled polymers before and after a single closed-loop recycling cycle. It was hypothesized that the formulation of a novel biocidal copper-based nanocomposite embedded in a biocompatible 3D printing polymer/copolymer can be used for the development of antimicrobial medical devices to mitigate microbial risks during long space flight missions. However, recyclability of plastic waste is critical in achieving a closed-loop recycling ecosystem envisioned for long duration space missions. Currently, ambiguity exists on the practicality of 3D printed thermoplastic recycling, processing protocols, and mechanical characteristics of these polymers, such as polylactic acid-based and polyurethane-based materials. Additionally, no current known research has been conducted on recycling these novel antimicrobial materials.
