Abstract:

In this study, EU-type diblock (mPEG-b-PCL) and BAB-type triblock (PCL-b-PEG-b-PCL) copolymers were synthesized by macro-initiating polymerization of e-kaprolactone (ε-CL) using mPEG (monometoxy poli(ethylene glycol)) and PEG (polyethylene glycol) respectively and catalytically using silk octanoate (Sn(Oct)2). In the block copolimer, colloidal solutions of Ag/PEG-b-PCL and Ag/PCL-b-PEG-b-PCL containing silver nanoparticles were produced by the reduction of silver nitrate (AgNO3) metal salts. The characterization of mPEG-b-PCL and PCL-b-PEG-b-PCL bloc copolymers is made using the GPC, FTIR and 1HNMR techniques. Silver nanoparticles in the hybrid structure have been observed by surface plasma resonance (SPR) wave length change and fluorescence emission spectrum. The rate of reduction of methylene blue, which is used as a model medicine in drug-transporting systems, in the presence of silver nanoparticles in polymers, has been studied.
