AI-Driven Inverse Design of Functionally Graded Bio-Nanocomposites for Sustainable High-Barrier Packaging
Abstract: Multilayer plastic packaging realizes high barrier performance through laminated heterogeneous structures, but the heterogeneous structure has severe end-of-life challenges caused by the interfacial incompatibility of materials and the poor recyclability. This study proposes the inverse design of functionally graded PLA-nanoclay composite films by reinforcement learning as a monolithic alternative to traditional multilayer systems. Twin-screw extrusion is designed as a continuous control Markov decision process, and proximal policy optimization (PPO) is …

A Critical Analysis of Cold Spray Coatings and its Tribological Performances
Abstract: Coatings are utilized for temperature barrier, protection against corrosion and wear etc. Cold spray is a solid-state processing method that is unique among thermal deposition procedures since it deposits particles at temperatures below their melting point. This technology does not involve particle melting, hence retaining the original properties of the materials. Increased coating strength is achieved by retaining of feedstock powder microstructures and characteristics, which prevents oxide formation and other …
