Nanocomposites prepared with a terpolymer of poly(L–lactide) (PLLA)–poly(ε–caprolactone) (PCL)–poly(ethylene glycol) (PEG) and partially oxidized carbon nanotubes (CNTspo) were synthesized characterized to evaluate their ability act as an effective nanocarrier the anticancer drug methotrexate. The homopolymers PLLA PCL through ring-opening polymerization (ROP) gel permeation chromatography (GPC). PLLA–PCL–PEG terpolymers four-step chemical route using oxalyl chloride linker agent analyzed 1H–NMR, 13C–NMR, FTIR spectroscopies. Additionally, nanocomposites FTIR, X-ray photoelectron spectroscopy (XPS), well differential scanning calorimetry (DSC) technique. XPS analysis revealed that chains are grafted onto CNTspo. Moreover, evaluations DSC strongly suggest PCL-rich domains preferentially oriented toward release tests exhibited “burst effect” profile, which was more evident in than nanocomposites. Five models used assess methotrexate’s vitro release. For nanocomposites, best fit experimental data obtained first-order model, whereas results from Korsmeyer–Peppas model indicated Fickian diffusion drives
