Abstract—The experimental results, which show the possibility of immobilization of tetra(4-tert-butyl)phthalo-
cyanine complex and its zinc complex on the surface of nonwoven polypropylene and lavsan materials. The alkali
etching method was used for activation of the polypropylene surface. It was shown that the modiﬁ ed polymeric
materials possess sorption activity relative to creatinine.
Phthalocyanines and their metal complexes immobi-
lized on the surface of the polymeric supports are used in
the development of new elements of electronic devices,
gas sensors, heterogeneous catalysts, medical materials
and drugs [1–3]. Immobilization of phthalocyanines is
realized by the formation of covalent, ionic, as well as
weaker electrostatic and hydrogen bonds with active
functional groups on the surface of the polymer support.
For metal complexes there is the possibility of coordina-
tion bonding due to the interaction of the central metal
ion with electron-donating groups of the polymer .
In the case of the chemically inert polymer it is evident
that surface should be preliminarily modiﬁ ed for binding
macroheterocyclic compounds. Modiﬁ cation includes,
generally, preactivation of polymer to form a chemi-
cally active surface functional groups, which are then
used as reactive sites for grafting of various biologically
or chemically active compounds. Modiﬁ cation without
changing the volume, chemical, and physico-mechanical
characteristics of the material imparts to it a new and
useful the qualities.
Chemical, radiation-chemical, photochemical, plas-
ma-chemical, and other treatments are used for activat-
ing the polymer surface [4–7].
The chemical methods
of activation of the polymer surface are a promising
direction. It opens up new possibilities for development
of materials with biological, catalytic, ion-exchange, and
Purpose of the study is to develop methods of
immobilization of tetra(4-tert-butyl)phthalocyanine

] on the
surface of activated polypropylene and lavsan materials
and examination of their sorption activity with respect
to creatinine, whose content in the blood of the case of
kidney diseases can be greater by an order of magnitude
than the norm.
The following materials were used in the study: non-
woven geotextile material made of isotactic polypropyl-
ene (PPG) of a speciﬁ c density of 200 g m
nonwoven material from polyethylene terephthalate
(PETPG) with the speciﬁ c density of 203 g m
