Study The Effect OF Temperature Degrees Range In Some
Optical Properties And Electrical Properties For Polymer
(Carboxymethyl Cellulose) High Viscosity
Abstract:
Optical and electrical properties had been studies in this research for
Carboxymethyl cellulose(CMC H.V.) dissolved in water for (
to ) gm/ml
concentrations in temperature ( 25  c,35  c,45  c
) . With respect to the optical
properties experimentally measured the absorption by (Cintra ), the refractive index by
(refract meter) and the turbidity by (turbidity meter) from this property can calculated,
coefficient of absorption, reflectance, coefficient of finesses ,Natural life time, Brewster
angle and critical angle. This results appeared that these properties are increasing
linearly or exponentially , except the critical angle and coefficient of finesses decrease
with increasing the concentration, but all these properties are increasing with
temperature increasingly ,except the critical angle .
The electrical conductivity had been measured by conductivity meter type
(elpha
) and from it can calculated molar conductivity and degree of dissociation.
these properties are decreasing exponentially with increasing the concentration, except
the electrical conductivity . while the results appeared that these properties are
increasing with increase temperature, except the degree of dissociation.
