Paragraph starter
The investigation into PLA/nanofibrillar cellulose composites by Wietecha et al. (2023) highlights that surface modification of cellulose nanofibers with various surfactants significantly enhances mechanical properties such as tensile strength and elongation at break. Crucially, these modifications do not impede the material's ability to disintegrate under composting conditions, offering a pathway for developing stronger, more sustainable biocomposite materials.
