Recent research from Montana State University is shedding light on the complex behavior of nanocrystalline cellulose (NCC) suspensions, a material that holds significant promise for various applications, including those in the construction sector. The study, led by Stanley Maribelle A. from the Chemical and Biological Engineering Department, utilizes advanced rheo-nuclear magnetic resonance (NMR) velocimetry to explore the intricate flow dynamics of NCC suspensions, revealing phenomena that standard rheometry often overlooks.
NCC, derived from cellulose, is known for its strength and lightweight properties, making it an attractive additive in composite materials. The findings from Maribelle’s research indicate that NCC suspensions exhibit diverse flow behaviors, such as wall-slip, shear banding, and yielding, which can significantly influence their performance in practical applications. “Understanding these flow behaviors allows us to tailor the processing conditions to optimize the microstructure of NCC suspensions,” Maribelle stated, emphasizing the potential for enhanced material properties.
The study highlights how large-velocity fluctuations in a chiral nematic liquid crystal-phase suspension can be linked to the orientation and movement of particles within the fluid. This insight is crucial for industries that rely on precise material formulations, such as construction, where the integrity and durability of composites are paramount. By controlling the microstructure of NCC suspensions, manufacturers can potentially improve the mechanical properties of construction materials, making them not only stronger but also more sustainable.
As the construction sector increasingly seeks eco-friendly alternatives, the ability to manipulate NCC suspensions could lead to breakthroughs in creating greener building materials. The research provides a foundation for future developments, suggesting that enhanced understanding of flow dynamics may yield composites that are both high-performing and environmentally friendly.
