Which technique is the most sensitive for the measuremt of glass transition temperature?

04 April 2014 1 7K Report

The dynamic mechanical analyzer is the most sensitive technique because the storage modulus of the glassy region can be more than 100 times larger than that of the rubbery region.

So it seems that you already have the answer. I agree that DMA (and even TMA) can be much more sensitive than DSC. However, it also depends on the shape and on the amount of sample. If you have a very thin film for example, DSC will be not enough accurate, whereas penetrometry through TMA will be perfect.

Is there an ideal incubation time of RGO-modified SPCE before subsequent use, i.e., electrochemical characterization or further modification?

I notice that upon washing and air-drying of my RGO/SPCE surface and characterizing again via DPV, the current response towards ferricyanide probe significantly decreases. My worry is that the...
