Abstract-Procedures were developed for chemical activation of polypropylene materials and subsequent
immobilization on them of the cobalt disulfophthalocyanine complex. Factors affecting these processes were
examined, and the state of the phthalocyanine on the surface of the polypropylene fiber was determined.
Because of the absence of polar groups on the
surface and in the bulk of the polymer, polypropylene
materials are very poorly dyed with all the types of
dyes, and their coloration is possible only through
structural modification .
The goals of this study were to develop methods
for modification of a nonwoven polypropylene materi-
al and for immobilization of the cobalt disulfophthalo-
cyanine complex (CoP) on activated polypropylene,
and also to examine how the concentrations of the
electrolyte and CoP affect the adsorption of the dye.
We used distilled water, o-xylene, H
(pure grade), HNO
(d = 1.36, chemically pure
grade), sodium peroxocarbonate (Khimprom Joint-
Stock Company, Novocheboksarsk, Chuvashia, Rus-
sia), and CoP (Zavolzhsk Chemical Plant, Joint-Stock
Company, Russia). We also used geotextile nonwoven
polypropylene material (GPP) produced by the Ka-
menskvolokno Joint-Stock Company with the surface
density of 400 g m
and thickness of 4 mm, and a
20-mm film of biaxially oriented isotactic polypropyl-
ene of molecular mass 4003700 kDa [TU RB (Techni-
cal Specifications of Belarus Republic) 00204079.164-
97]. The absorption spectra were recorded on a
U-2000 spectrophotometer, and the IR MATIR spec-
tra, on an Avatar 360 FT-IR spectrometer. The specif-
ic surface area of GPP was determined on a Sorbto-
metr-M surface area analyzer. The photomicrographs
of polypropylene films were obtained with an Axio-
star plus microscope. Polypropylene was activated by
Activation with hydrogen peroxide. A round-
bottomed flask equipped with a reflux condenser was
charged with 100 ml of 35% aqueous H
and 2 g
of GPP (four 0.5-g specimens), after which 5 mg of
was added (larger amounts impart a brown
color to polypropylene, and smaller amounts do not
ensure efficient catalysis of H
The reaction mixture was heated to boil and refluxed
for various periods. The start of boiling was consid-
ered as the start of the reaction. After the activation,
the specimens were washed with distilled water, dried
in air, and analyzed by IR MATIR spectroscopy. The
results obtained with different activating agents and
at different activation times are listed in Table 1.
Activation with sodium peroxocarbonate.
A 500-ml round-bottomed flask equipped with a reflux
condenser was charged with 2 g of GLL (four 0.5-g
specimens) and 200 ml of 5% NaOH. The mixture was
heated to boil, and 10 g of sodium peroxocarbonate
was added in small portions over a period of 1 h, so
as to ensure continuous evolution of oxygen. The
specimens were withdrawn and immersed in a fresh
5% NaOH solution, after which another 10 g of sodi-
um peroxocarbonate was added over a period of 1 h.
The thus treated specimens were washed with distilled
Activation in NaBrO solution. The activation pro-
cedure is based on the NaBrO synthesis protocol .
A 250-ml flask equipped with a reflux condenser was
charged with 2 g of GPP, and 100 ml of 40% NaOH
