Preparation of Recycled Polyamide by Using Dissolution/Precipitation Method

Dissolution/precipitation method is the one method to recycle polyamide or known as nylon. The dissolution method is done byusing solvent that can dissolve the nylon from the used nylon materials. The solvent that had been used in this experiment is formic acid, methanol and ethanol. For the precipitation process, methanol is used for changing back the nylon into precipitate form. The result shows that the formic acid can dissolve the nylon in the form of liquid after dissolution process had been done. The formic acid also has been mix with methanol or ethanol to reduce the effect of degradation of properties in nylon. The result from FTIR also shows that the recycled nylon still in form ofnylon. This shows that the recycling ofnylon can bedone byusing this method.
