Abstract—A possibility of directional control of engineering and operational properties of epoxy composites by
the use of small additions of potassium polytitanate nanoparticles, introduction of plasticizers of multifunctional
action, and methods of chemical and mechanical activation of components of the composition and the composi-
tion as a whole was demonstrated that provides development of epoxy composites of a new generation with high
performance parameters, which meet the requirements of most industries.
In recent years the various new types of powdered
ceramic materials based on refractory oxides (ﬁ brous,
layered, submicron, and nano-dispersed) are in great
attention since they has great potential use in the
manufacture of refractories, ceramics, ﬁ llers of polymer,
metal, and ceramic composite materials, mineral
pigments, sorbents, catalysts. Though for their production
various methods have been developed, however,
plasma-chemical synthesis, detonation method, vacuum
sublimation, gas phase reactions, mechanochemical and
chemical synthesis methods are the most widely used
Despite broad prospects of practical application
relatively little attention is paid to synthesis, research,
and practical application of a fairly new class of ceramic
materials: potassium polytitanate (PPT).
of the molten salts is the most effective and inexpensive
method for their preparation . Depending on the
synthesis conditions and chemical composition they are
either amorphous compounds with a layered structure
or crystalline submicro- and nanoﬁ bers [4, 5]. Layered
structures are characterized by low energy of interlayer
shear and high values of reﬂ ection and absorption in the
visible and infrared regions of the spectrum. Due to the
high capability to intercalate and catalytic activity they
can be used as catalysts in [1–4], ion exchange materials,
and solid electrolytes and phosphors. PPT protonated to
pH 7 also can be applied.
Such variation in the structure and, respectively,
properties, allows considering potassium polytitanates as
promising material for applying in various ﬁ elds of tech-
nology. Potassium titanates of a general chemical formula
represent a new kind of functional materials,
the structure of which depends on the ratio of the oxides
O and nTiO
and on a synthesis temperature .
Potassium titanates properties permit their use as
relatively cheap ﬁ llers of polymer and metal matrix
composites, which provide reaching high mechanical
strength, reducing the coefﬁ cient of friction and increase
in heat resistance [1–5].
In studies an epoxy resin of a grade ED-20 (GOST
10587-93) was used modiﬁ ed with trichlorophosphate
(TCP) (TU 6-05-1611-78) containing ﬂ ame retardants in
the composition: phosphorus and chlorine, which act as
structure-forming agents for epoxy resin when it subjected
