Small-angle neutron differential scattering

Figure 5 - Small angle neutron differential scattering cross section (ooo) measured from a sample consisting of sheets of PIP (N = 23000) and deuterated 1,2-PBD (N = 3200) which were in contact for 162 hours at 52°C. The scattering contrast significantly exceeds the incoherent background (—) determined from measurements on the individual polymers, evidencing the thermodynamic miscibility of the blend.

In a previous study of fumed silica by mercury porosimetry (ref. 1), we established an inverse dependence of the powder compressibility k on applied pressure P, heralded by power-law differential volume vs pressure curves. Independent small-angle neutron scattering (SANS) measurements, undertaken to establish microstructure, indicated a decreasing zero-angle intensity, I(q- 0), with increasing sample compression. [Pg.267]
