## Abstract

This study examined an iron-assisted cold plasma (CP) approach for converting pineapple peel cellulose into cellulose nanofibrils (CNF). The process involved pre-absorption of iron onto cellulose, followed by 60 minutes of CP exposure and subsequent ultrasonication to achieve nanofibrillation. The combined Fe-CP pretreatment markedly reduced the degree of cellulose polymerization and promoted electrostatic repulsion among fibrils. Surface analysis revealed increased roughness and structural breakage on pretreated cellulose. Additionally, intermolecular hydrogen bond content and average crystallite size both decreased significantly. These findings offer mechanistic insight into Fe-CP and cellulose interactions, contributing foundational knowledge for developing efficient cellulose disintegration strategies.

### Mechanism

Iron pre-absorption followed by cold plasma exposure reduces cellulose polymerization degree, decreases intermolecular hydrogen bonds, and lowers crystallite size, while enhancing electrostatic repulsion between fibrils to facilitate nanofibrillation.

## Delivery context

This is basic research at the cellular or molecular level. For human application, inhalation is the most promising delivery route, but inhalation carries explosion risk and concentration matters (empirical LFL of 10%; high-concentration devices are not recommended).
