1 Introduction
Modern science is moving toward the creation of effective heterogeneous organoinorganic systems that provide the appearance of a number of new physicochemical
properties that are not inherent in the individual components that form such systems.
Inorganic–organic hybrid nanocomposites are a class of materials defined as inorganic nanostructures included in an organic matrix, where both the constituents of
the hybrid system show characteristics different from the ones they would have in
the absence of the other [1–3]. Hybrid polymer nanocomposites are considered to be
promising materials for a variety of technological applications due to their unique
electronic, optical, and sensory properties. Interest in polymer–metal nanosystems is
conditioned by the possibility of obtaining materials with new, enhanced functional
properties that can be applied in sensor and medical chemistry, electrocatalysis, and
biotechnology [4–7].
Understanding the physicochemical processes occurring in such systems is key
to creating a new generation of functional devices and, at the same time, makes
their manufacturing technology reliable and manageable. Collaborative studies by
physicists, chemists, and material scientists have shown that reducing the particle size
of metals (especially noble ones—Ag, Pt, Au, Pd) to the nanometer scale leads to new
crystalline modifications or even new physical phenomena not peculiar to materials
with micron-sized particles. The prevention of aggregation of nanoparticles with
excess surface energy and the preservation of their unique properties is possible by
the creation of composites with polymer matrices by the mechanism of encapsulation
