Pdms shear thinning
Spletstudy samples with zero-shear viscosities in the 10 – 50 Pas range or below [2, 13]. Only a few papers consider silicone oils with much higher viscosities [14, 15]. A detailed investigation of shear thinning [16] and a thor-ough analysis of the relaxation times [17] in high vis-cosity PDMS give valuable information about their rhe- SpletUnfortunately, the combination of as little as a few weight percent of untreated fumed silica nanoparticles [uFSN] with a siloxane polymer, such as PDMS, forms a difficult to process waxy solid admixture that even long periods of high shear mixing will not thin.
