You should do this:

import common.interface.interface

later do this:
    self.ui = common.interface.interface.Ui_Materials()


If you are annoyed by the long names you can do this:

import common.interface.interface as ci

then

self.ui = ci.Ui_Materials.

Look up the section in python.org on importing modules to learn more
