Abstract
Adhesion force mapping using atomic force microscopy has been used to inves tigate a phase-separated blend of poly(methyl methacrylate) (PMMA) and poly (dodecyl methacrylate) (PDDMA). Comparison of the results from the blend wi th those from the pure constituent polymers showed that force mapping could identify PMMA- and PDDMA-rich areas in the blend. The adhesion maps produc ed were deconvoluted from sample topography and contrasted with data obtain ed from contact angle goniometry.
