Abstract
The present work includes three chapter
Chapter (1): Introduction:
This chapter contains the kinetic of the anodic oxidative electropolymerization of aniline, pyrrole and their derivatives, characterization of the obtained polymer films by cyclic voltammetry, UV-Visible, IR, 1HNMR spectroscopy, X-ray diffraction studies, morphological investigated by SEM, thermal stability by TGA, molecular weight and molecular weight and molecular weight distribution by GPC, physical properties and structure of polymers which have been discussed in literature.
Chapter (2): Experimental:
Comprises the chemicals, experimental methods for the electropolymerization, cyclic voltammetry, corrosion protection, computer softwares, Techniques for the kinetic studies and caculations of the reaction order and activation thermodynamic parameters are given. characterization of the obtained polymer films by different instrumental techniques such as UV-Visible, IR, 1HNMR, elemental analysis, GPC, TGA, XRD and SEM is also given. The as conductivity cell for the conductivity measurements is described.
Chapter (3): Results and discussion:
This chapter includes the layout of the obtained results and their discussions and consists of four parts:
Part (1):
In this part, the kinetic of the oxidative electropolymerization of O-aminobenzoic acid, O-aminophenol and a binary mixture of O-aminobenzoic avid and Pyrrole in acid medium in presence of supporting electrolyte (Na2SO4) at different temperatures under nitrogen atmosphere were investigated. The reaction rate law of the above electropolymerization system are given by the following equation:
The mechanism of the anodic oxidative electropolymerization in each investigated monomer type in HCL medium is suggested. The copolymer composition was investigated by the determination of r1 &r2 by Fineman-R oss method and it was found to be block in nature.
Part (2):
This part includes the cyclic voltammetry measurements of the polymer formation in each case, the obtained results reveal the following:
In case of (O-aminobenzoic acid) it is clear that the voltammogram exhibits three anodic peaks at – 280, +970 and -50 mV vs. SCE respectively and two cathodic peaks appear at +430 and +30 mV vs. SCE respectively.
In case of (O-aminophenol) it is clear that the voltammogram exhibits two oxidation peaks at -300, +810 mV vs. SCE respectively and one cathodic peak which appears at +25 mV vs. SCE
In case of (a binary mixture), we found four anodic peaks at -400, +1100, +1400 and -250 mV vs. SCE respectively and the reverse scan does not include any cathodic peak. Also, the oxidation potentials of the binary mixture are shifted to higher values than that of two separate monomers.
The all investigated systems realize the electroformation of radical cation in each case may be described partially by diffusion-controlled process.
Part (3):
In this part, the characterization of all obtained polymer films at optimum conditions which gives homogenous and good adhered film were investigated. The characterization tools are elemental analysis, absorption spectroscopy using IR, UV-Visible and 1HNMR instruments. X-ray diffraction analyses for determination of polymer crystallinity are also investigated. This study assures that all the investigated polymer films are crystalline structure. This is also confirmed by scanning electron microscope investigated, which give an idea about the morphology.
Thermal analysis (TGA) is also investigated which confirm the suggested structure of the prepared polymers. Molecular weight values (Mw, Mv, & Mn) and polydispersity of the prepared polymers were determined by GPC analysis. It was found that the molecular weight values of the prepared polymers have the following order:
P(OABA-co-Py) < P(OAP) < Ppy < P(OABA)
The polydispersity have the following order:
P(Py) < P(OAP) < P(OABA) < P(OABA-co-Py
The ac conductivity for the prepared polymers was measured and the conductivity values (σ) were found to be in the following order:
Ppy < P(OABA-co-Py) < P(OABA) < P(OAP)
Part (4):
This part includes the application of the prepared polymer samples as corrosion protection for mild steel samples in different medium.
All the prepared polymers have a protective effect on mild steel
