Synthesis and characterization of poly (linoleic acid)-g-poly(methyl methacrylate) graft copolymer with applying in Au/PLiMMA/n-Si diode

Poly (linoleic acid)-g-poly(methyl methacrylate) (PLiMMA) graft copolymer was synthesized and characterized. PLiMMA graft copolymer was synthesized from polymeric linoleic acid peroxide (PLina) possessing peroxide groups in the main chain by free radical polymerization of methyl methacrylate. Later, PLiMMA was characterized by proton nuclear magnetic resonance (H-1 NMR), gel permeation chromatography (GPC), thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) techniques. Furthermore, Au/PLiMMA/n-Si diode was fabricated for the purpose of investigating PLiMMA's conformity in diodes. The main electrical characteristics of this diode were investigated using experimental current-voltage (I-V) measurements in dark and at room temperature. Obtained results, such as sufficiently high rectifying ratio of 4.5 x 10(4), indicate that PLiMMA is a promising organic material for electronic device applications. (C) 2014 Elsevier Ltd.
