Figure 8.15 (a) Concentration profiles of in bilayer samples of P3HT and rf-[60]PCBM annealed for 5 min at different temperatures as measured using dynamic secondary ion mass spectrometry (DSIMS). The thicknesses of the layers were normalized such that 0 nm is the... 

The reptation dynamics and the interface structure relations in Table 2 have been demonstrated experimentally by a series of interdiffusion experiments with selectively deuterated HDH/DHD polymer interfaces using dynamic secondary ion mass spectroscopy (DSIMS - see Secondary ion mass spectrometry) and neutron reflectivity. The scaling laws for interdigitation and the complete concentration profiles for Rouse and reptation dynamics have also been calculated. ... 

The chemical mapping of simple ions such as C, Na, and have been applied to the TOF-SIMS analysis of biological samples of organs, tissues, and cells [22-27,89,90], and 3D images of the elemental distributions [91] have also been obtained. In addition, lateral and 3D distributions of Na+, K+, Ca+, and isotope-labeled elements in cells can be obtained with dynamic secondary ion mass spectrometry (DSIMS) imaging techniques [91,92].

Data Acquisition Once the sample has been successfully inserted, then data acquisition is initiated. Typically, the ionization period is kept as short as possible (1 ms), to minimize the number of ions created in the experiment. Ions are formed, then scanned out continuously (in the positive-ion mode), and hence, mass spectrometry as a function of extraction time is a key feature of the DSIMS experiment. 

Molecular aggregation structure of the PS-PFACg diblock copolymer films along the normal direction to the surface was also examined by dynamic secondary ion mass spectrometry (DSIMS), which is a well-established tool for the depth profiling of polymer materials. The PFA weight fraction at the depth of z by DSIMS was given as follows.
