He is best known for his work on the
small-angle X-ray scattering method, done in collaboration with his teacher
Otto Kratky, and in particular for
Porod's law In X-ray or neutron small-angle scattering (SAS), Porod's law, discovered by Günther Porod, describes the asymptote of the scattering intensity ''I(q)'' for large scattering wavenumbers ''q''.

The worm-like chain (WLC) model in polymer physics is used to describe the behavior of polymers that are semi-flexible: fairly stiff with successive segments pointing in roughly the same direction, and with persistence length within a few orders of ...
model, introduced in a 1949 paper, is sometimes called the Kratky–Porod model.
In 1965 Porod was appointed as professor of experimental physics at the university of Graz.
In 1978, he was awarded the
Erwin Schrödinger-Preis.
