All materials do not act as conductors because of absence of free electrons.
To answer this question well, lets understand what an electric conductor is.
A conductor is any substance that conducts electricity. And this can be done by displacing charged particles.
In most of the cases these charged particles are electrons. Metallic substances have free electrons and hence they act as conductors.
In ionic conduction, the 'charged particles' mentioned above are ions in a solution.
But since all the substances do not have free electrons or do not possess free ions, all substances are do not act as conductors.
Some examples of non conductors of electricity are:
Wood, paper(most of the organic compounds), Pure water, air, and so on.

HEYA MATE HERE U GO
in conductors the gap between the atoms is very less so the transfer of energy is easy but in other materials the gap is more so the transfer of energy is not possible.
HOPE THIS WILL HELP U
