Figure 8. (A) DSC analysis of ECAs containing 5 vol% silver and varying of PEG 200 content. The heat flow of pure PEG 200 is shown as reference. The lower diagram depicts the temperature range from -100 to -40 °C, while the upper diagram provides a detailed view of the temperature range between -100 and -70 °C. All measurements were performed at a heating rate of 10 K·min^-1; (B) Mean relative absorbance of epoxy-polar liquid-PEG 200 mixtures as a function of PEG 200 content, determined at a wavelength of 600 nm using an Implen OD600. The dashed line is to guide the eye. The squares indicate the mean values, and the error bars denote the standard deviation obtained from 3 measurements. ECA: Electrically conductive adhesive; PEG: polyethylene glycol; DSC: differential scanning calorimetry.
