Tensile Testing of Hydrogel Fibers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Tensile tests on dry and wet hydrogel fibre bundles were performed with a DMA Q800 unit from TA Instruments. Sample diameters were determined using a light microscope. For wet strings, samples were stretched to break within 30 sec to minimize the effect of water evaporation on measurement. The Young’s moduli were calculated within the initial linear region of the stress-strain curves from the tests.

Dynamic Mechanical Analysis of CNF Membranes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Dynamic mechanical analysis (DMA) was performed on membranes with increased CNF loading (4 to 20%) using a DMAQ800 unit (TA Instruments, New Castle, DE, USA) operating under tensile testing mode, and using a preload of 0.1 N. The gauge length was adjusted to 14 mm. The measurements were performed at a constant temperature (30C) and a sinusoidal (dynamic) tensile load (1 kHz) was applied to produce a dynamic strain with constant amplitude of 0.05%.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
