Accurate quantification of cellulosic materials remains a difficult technical challenge in applications. In this work, we describe a new procedure to form amorphous cellulose spheres with diameters on the order of millimeters in size. The spheres can be obtained with minimal roughness, typically 1-2 nm in root mean square values. Implementing a custom-built contact adhesion apparatus, we utilize these smooth probes to quantify adhesion that previously has not been observed. In the final part of the study, we create functionalized surfaces through established organic and polymer chemistry. We demonstrate the ability to implement novel polymerizations to create unique cellulosic interfaces. The modifications are then quantified through the contact adhesion testing to measure the differences in interfacial strength. Furthermore, we evaluate the polymer dynamics that are involved in the contact adhesion testing.
