Found that in the presence of a crosslinking most. Solution epoxy concentration of 0.82 M, the addition of the catalyst and controls the pH value of no less than 12.4 hours plated 24 hours, the temperature in the dryer after treatment at 100 ° C for 36 minutes to check. Check with Fourier transformer infrared spectrometer Four Masters meter (FT-IR) showed the functional groups of the crosslinking reaction between nitrogen of amino groups in silk and carbon. The resin, which has yet to appear. In addition, analysis by electron microscopy, SEM (SEM) showed that the surface of the silk improvements are resin coated on a rough surface. Shows clearly that the crosslinking up.
