A new type of insulating wood pulp-polymer complexes paper sheets has been developed. The effect of variation of pH-value, during preparation process, on mechanical properties of the prepared sheets was studied. The prepared sheets were also subjected to electrical and IR-spectrophotometric: studies. The results obtained show that the type of polymer ligand (HEC, PVA & CMC), cation (Fe3+ & Zn2-) and anion (Cl- & NO3-) of the metal salts of polymer complex, in addition to the pH-value have a profound effect on the mechanical properties of the prepared-sheets. The optimum properties were obtained in case of beater addition CMC-Zn(II) complex at pH 6.62. The high insulation properties of the prepared sheets containing polymer complexes [CMC-ZnCl2 & CMC-Fe(NO3)3] were noticed, compared with those obtained from addition of metal salts (FeCl3) or wood pulp without additives. The results of dielectric constant (ε') and dielectric loss (ε'') in some cases are in good agreement with the IR-measurements. However, the IR-measurements are in agreement with the strength properties. |
