This study reports the preparation of a polybutylene succinate (PBS) film reinforced with pure cellulose nanofibril (PCNF) and lignocellulose nanofibril (LCNF) by a two-step process that consists of solvent dispersion and twin-screw extrusion. Compared to the conventional one-step process, this method offered improved mechanical properties. The addition of 5% CNF increased the tensile properties up to 18.

Article Synopsis
  • A cellulose acetate (CA)/cellulose nanofibril (CNF) film was created using a solvent casting method, where CNF serves as a reinforcement to enhance the film's tensile strength.
  • The study tested different ratios of CNF (3, 5, and 10 parts per hundred) and experimented with eco-friendly plasticizers (triacetin and triethyl citrate) along with two solvents (acetone and NMP).
  • Results indicated that using NMP for dispersion improved the film's mechanical properties significantly, with up to a 38% increase in tensile strength and a 65% increase in elastic modulus compared to pure CA, especially with a maximum effective CNF loading of 5 phr.

Lignocellulose nanofibrils (LCNFs) with different lignin contents were prepared using choline chloride (ChCl)/lactic acid (LA), deep eutectic solvent (DES) pretreatment, and subsequent mechanical defibrillation. The LCNFs had a diameter of 15.3-18.

We aimed to improve the mechanical properties of alginate fibers by reinforcing with various cellulose nanofibrils (CNFs). Pure cellulose nanofibril (PCNF), lignocellulose nanofibril (LCNF) obtained via deep eutectic solvent (DES) pretreatment, and TEMPO-oxidized lignocellulose nanofibril (TOLCNF) were employed. Sodium alginate (AL) was mixed with PCNF, LCNF, and TOLCNF with a CNF content of 5-30%.
