Some embodiments include a method of preparing polymer nanofiber composites using a cross-linkable polymer precursor solvated with a solvent, and forming a nanofiber precursor by mixing with a metal-organic-framework (MOF) crystal material that includes a metal ion coupled to at least one multidentate ligand. Further, the method can include forming a plurality of nanofibers by electro-spinning the nanofiber precursor, where at least a portion of the nanofibers includes a dispersion of the first MOF crystal material. The method can include crosslinking the plurality of nanofibers by irradiating the plurality of nanofibers with UV light, IR light, visible light, gamma radiation, and/or electro-beam radiation. Further, the method can include applying a second MOF crystal material between the cross-linked nanofibers and the first MOF material.

A method including applying a wetting agent to air-laid pulp to form an intermediate pulp and cold-pressing the intermediate pulp to form a moulded product. The pulp may be formed from a fibrous raw material. The wetting agent may include a functional additive such as a sol. A sol may include a solvent, an alkoxide, and optionally a catalyst. The air-laid pulp, intermediate pulp, and/or moulded product may be free or substantially free of thermoplastic polymers and/or hydrocarbon-based plastics. The moulded product may be a fibre-based bubble wrap. The fibre-based bubble wrap may be formed from reel-to-reel processes.

A method of entrapping a material with at least one nanoscale dimension within a mesoporous fiber welded biopolymer, comprising the steps of preparing a colloidal suspension (wherein the colloidal suspension contains one or more materials with nanoscale dimensions in a compatible solvent), exposing a mesoporous fiber welded biopolymer to the colloidal suspension, entrapping within the mesoporous fiber welded biopolymer one or more materials with nanoscale dimensions, and removing solvent from the resulting composite. A mesoporous natural fiber welded biopolymer material with entrapped materials of nanoscale dimensions which exhibits properties and/or functions that are the combination of those from the mesoporous fiber welded biopolymer and the entrapped material(s) with nanoscale dimensions.
