Scaled intensity C*I(q) versus wave vector q profile for a. SiO2–PEG450/PEG50k, SiO2–PEG450/PEG203k, SiO2–PEG450/PMMA280k and SiO2–PEG2k/PMMA280k at φ=2%. The insets (i), (ii) and (iii) are transmission electron micrographs of the SiO2–PEG450/PEG50k, SiO2–PEG450/PEG203k and SiO2–PEG2k/PMMA280k materials, respectively. (b) SiO2–PEG2k/PMMA55k\165k\280k at φ=0.5% (circles), 1% (diamonds), 2% (upright triangles), 5% (inverted triangles) and 10% (squares). I(q) curves are displaced vertically for clarity of presentation. Scale bars in the TEM images represent the length of 200 nm. C is a scaling factor used to displace I(q) curves vertically in both the plots, for clarity of presentation. Errors in I(q) are the s.d.’s of the counts on the two-dimensional detector pixels with same q value, with the I(q) being the mean of all those values. The error bars shown in the figure are consistently smaller than the symbols.
