Molecularly imprinted polymers (MIP) were prepared by bulk polymerization using
indole-3-acetic acid (IAA) as a template molecule with methacrylic acid (MAA) or
methyl methacrylic acid (MMA) as functional monomers and ethylene glycol
dimethacrylate (EGDMA) as cross-linkers. By using fourier-transform infrared
spectroscopy (FTIR) all the functional groups presence in the polymers were detected.
Characterization using scanning electron microscopy (SEM) shows that polymers
formed irregular shape for all polymers that have been synthesized. It can be seen
that imprinted polymers surface are rougher compare to the non-imprinted polymers.
For the characterization using Brunauer–Emmett–Teller (BET) shows that MIP IAA MAA
have pore size (21.441 A ° ) and MIP IAA MMA have pore size (21.469 A ° ).Binding studies
showed that MIP IAA MMA have higher affinity than MIP IAA MAA .
