SANS and Rheology Data for Surfactant-Cellulose Nanofibril Hydrogels

Marcelo Alves da Silva from the University of Bath provides a dataset of small-angle neutron scattering (SANS) curves, fits, and oscillatory shear rheology measurements. The data characterize the impact of various wormlike micelle-forming surfactants on the nano and macroscopic structure of TEMPO-oxidized cellulose nanofibril hydrogels. Measurements were taken across different surfactant concentrations and mixtures in aqueous sodium chloride and heavy water environments.

Use Cases

• Modeling nanostructural parameters based on SANS curves and fits for different surfactant systems.
• Analyzing viscoelastic properties based on oscillatory shear frequency and amplitude sweep data.
• Investigating the effect of surfactant concentration and mixture composition on hydrogel microstructure.
• Correlating macroscopic rheological behavior with nanoscale structural data from SANS.

Strengths

• Includes complementary nanoscale (SANS) and macroscale (rheology) characterization data.
• Covers multiple surfactant systems (CAPB, CAPOx, SLS, SDS) and their binary mixtures.
• Data is provided for systems in both pure heavy water and cellulose nanofibril hydrogel matrices.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
