The mechanical properties of water-swollen APCNs were consistently lower than those samples swollen in n-hexane or dry samples. The maximum stress-at-break was 1.2 ± 0.2 MPa for the 9 wt% HCNCs. This value is similar for all samples up to 22 wt% CNCs, with all values remaining within the margin of error. The highest strain-at-break was recorded for the 3 wt% samples with 104 ± 70 %. However, this value has a broader standard deviation compared to the other CNC concentrations, possibly because the CNCs are not homogeneously distributed within the sample, acting as failure dissipation regions. Therefore, further studies are needed for this composition.
