Nanomechanical properties of poly(methyl methacrylate-co-9-anthryl methyl methacrylate)

Add time:08/13/2019    Source:sciencedirect.com

The proximity of anthryl groups is an important factor governing opto-electronic and film properties of anthracene containing polymers used in technological applications. The surface mechanical properties of a series of poly(methyl methacrylate-co-9-anthryl methyl methacrylate) are described. The anthryl group content (wt.%) in copolymers was 20%, 9.1%, 3.8% and 2.8% corresponding to one chromophore interspersed between each 4, 10, 25 and 35 methyl methacrylate units. The effect of the concentration of anthracene on the nanomechanical properties such as hardness, elastic modulus and viscosity is discussed in terms of chain mobility.
