Abstract
A Melamine molecularly imprinted polymer has been successfully produced with cooling-heating method. A melamine as template was entered into methanol and aquabides solvent, then added methacrylic acid (MAA) as monomer, ethylene glycol dimethacrylate (EDMA) as cross-linker and benzoil peroxide (BPO) as initiator. The pre-polymer solution was then stirred at 40°C temperature for 15 minutes. The solution was then entered into vials. The vials were then cooled in freezer at -5°C temperature for 1 hour. After cooling process, vials were heated in furnace at 75°C held for 3 hours, 80°C held for 3 hours and 85°C held for 1 hour. After vials were heated, the pre-polymerization solution has changed into solid polymer. The solid polymer was then ground to powder. The melamine template was then removed from polymer with methanol solvent. Polymer after template removal process called as MIP. Solid polymer and MIP was then characterized with FTIR and SEM. FTIR result showed that solid polymer has %transmittance is smaller than MIP at wavenumber amines group. FTIR result indicated that melamine level in MIP was decrease. SEM result showed that solid polymer has 247 cavities and MIP has 318 cavities. Cavities in MIP were formed because melamine in polymer has lost.
