Coulombic force between two charges depends on magnitude of their charge, their separation and the electrical permittivity of the medium in which charges are placed. so, it seems that coulombic force is independent of temperature but in actual electrical permittivity depends a little on temperature and hence coulombic force indirectly depends upon temperature.
but dependence of electrical permittivity on temperature is complicated and it depends upon nature of medium, types of bonds of medium and on many more parametres and that explanation is beyond the scope of this discussion.
so at this level we can say that coulombic forces are independent of temperature.
