What is the range of absorption coefficient of PANi nano fibers dispersed solution?

12 December 2017 1 9K Report

The UV-Vis absorption coefficient of PANi nano fibers dispersed in water is very low. What are the possible reasons behind this low value?

Hugh J Byrne

Absorption in solution is dependent on concentration, so increasing the concentration will increase the absorption.

The peaks at~4.2 eV, 5eV and 6eV are already saturated, however, your HOMO-LUMO looks like it is at 2.3 eV or even lower.

How can I explain that the residual stress can shift some xrd peaks in one direction, and other peaks in the opposite direction for the same sample?

This is may be due to the need to balance stress at grain boundaries, and satisfy constraints on the strain tensor (for example a tensile stress along one direction must be balanced by a...

Why does a photon transfer all its energy to an electron (and disappears) rather than transferring part of its energy and continuing to exist?

The photon CAN transfer part of its energy to the electron and continue to exist. An example of this is Compton scattering, where a gamma ray transfers enough energy to the electron to ionize and...
