Implication

Investigates how cellulose source and low-temperature hydrolysis affect CNC morphology, suggesting new designs for cellulose-based materials.

Key Points

The research aims to understand how different cellulose sources and pretreatments affect the structure and morphology of cellulose nanocrystals obtained through low-temperature acid hydrolysis.
Conducted sulfuric acid hydrolysis at room temperature.
Compared hemp pulp, micronized cellulose powder, and microfibrillated cellulose in native and mercerized forms.
Analyzed the impact of hydrolysis conditions on CNC structure and morphology.
Identified distinct crystalline structures and non-classical morphologies in CNCs.
Obtained rod-like, hierarchical, and flake-like nanoparticles.
Measured average lengths of larger particles at approximately 320 nm, with smaller cellulose II crystallites averaging 45 nm in length.
