Polymer Technology – Novel
Plastics with Germicidal Effect
Germs are found in all areas of everyday life and can lead
to dangerous infections. To reduce the risk of infection in
sanitary facilities and hospitals, surfaces with antimicrobial
properties can be used. The aim of the project AntiMik
is to obtain polymer compounds with antimicrobial
properties for the preventive reduction of microorganisms
in the health care sector. Nano-scale, photocatalytically
active titanium dioxide (TiO
2
) is incorporated into different
polymer matrix systems. The TiO
2
induces radicals on the
surface that have the potential to kill germs. The objective
of this project is to identify and process matrix-filler com-
binations with a high germ reduction rate and resistance
against material ageing.

Approximately 1 billion people live in so-called least devel-
oped countries (LDC). Driven by the initiative of the students,
the project ‘MedTech for LDC’ creates a knowledge and
cooperation basis for the development of medical devices
that can be manufactured and marketed under the condi-
tions in LDCs. In a first approach, a cooperation was
established with Addis Ababa University and the
NGO Cheshire Services Ethiopia, which provide the
children of the poorest with simple prostheses.
