Abstract Scope |
We present an overview of the various factors affecting the precision and accuracy of the nanoindentation test results at different test conditions with specific focus on Continuous Stiffness Measurement (CSM) technique. As an example of the use of this technique we present results documenting the response of N95 mask microfibers to UV light exposures that are proposed as disinfecting techniques to allow mask reuse. The hardness and modulus of the fibers show significant changes as the exposure is increased. This gives some guidelines as to how many times the masks may be used. |
