Introduction Nowadays, plastic debris has gained recognition globally as an emerging environmental issue exacerbated by extensive production and incorrect disposal (Andrady, 2011). Plastics have been widely used as basic components in industrial, commercial, and municipal applications due to their durability, affordability, and convenience (Roy et al., 2011).

Mn-based tunnel-structured Na0.44MnO2 cathode materials for high-performance sodium-ion batteries: electrochemical mechanism, synthesis and modifications Sodium-ion batteries (SIBs) have emerged as promising and mature alternatives to lithium-ion batteries (LIBs) in the post-LIB era, necessitating the development of cost-effective and high-performance cathode materials.

Nature has been an important source for the inspiration and innovation of new materials and technologies in human society. Many creatures have unique properties owing to their special microstructures. For instance, the anisotropic porous structure of bamboo and balsa wood is not only conducive to the transmission of water and nutrients, but also gives them extremely strong axial strength and radial toughness [1], [2], [3], [4], [5], [6].
