Determination of oligomeric chain length distributions at surfaces using tof sims segregation effects and polymer properties it was determined that the surface pdms segment length distributions were consistently shifted towards higher masses than the distributions measured in the bulk tof sims analysis of thick copolymer films in the . Polymer surface structures determined using tof sims concentric ringed structure in a 190 nm thick ba c6 film acid and polymer films surface chemistry and chemical structures studied by . This multi technique approach is used to examine polymer segment distribution at the surface to examine the mechanism of biodegradation of polymers and to examine polymer tertiary structure at the surface extensive outreach to the local community and the development of science education materials is an important aspect of this work. The transfer of organics onto glass studied by tof sims article in surface and interface analysis 431 2 february 2011 with 5 reads doi 101002 sia3632. Tof sims has been shown to be very useful in surface characterizations of polymer materials16810 20 the secondary fragments emitted from a polymer surface are directly related to the surface molecular structure21 23 however there is no direct relationship between the surface chemical composition and the tof sims peak intensities
