Στην εργασία μελετάται η ενίσχυση των μηχανικών ιδιοτήτων πολυμερούς, όταν σε αυτό εισαχθούν νανοσωλήνες άνθρακα.Υπολογίζονται τα μέτρα ελαστικότητας νανοσωλήνων άνθρακα διαφόρων μεγεθών και το μέτρο ελαστικότητας δικτύου πολυαιθυλενίου. Ελέγχεται η επίδραση της διαμέτρου, του προσανατολισμού και του πλήθους των νανοσωλήνων στο μέτρο ελαστικότητας του συνθέτου υλικού και τα αποτελέσματα συγκρίνονται με το νόμο των μιγμάτων. Η μέθοδος που χρησιμοποιείται για τη μελέτη των συστημάτων είναι η Μοριακή Δυναμική. |

Nanomaterials have been the centre of attention of material science for the past few
years and constitute
an important
field of research
worldwide
due to their exceptional
properties, which make them suitable for
a high number
of
applications. At the same time,
polymers are an integral part of modern life as they are used in a wide range of
technological
and
everyday applications and are
supported b
y huge industrial production.
The combination of polymers and nanomaterials creates a new class of materials called
nanocomposites. T
hrough these materials promise the expansion of
the applications of
polymers
is feasible
, as they
ensure
significant improv
ement to
the
mecha
nical and electrical
properties of the polymer, as well a
s maintenance of its
low density.
This pa
per focuses on the study of the
enhancement
of the mech
anical properties of a
polyethylene matrix when carbon nanotu
bes are introduced into
it. It is also concerned with
the influence of diameter, orientation and number of nanotubes on the final modulus of
elasticity of th
e composite material as well as with the comparison of the experimental
modulus of elasticity with the theoretical modulus
that is calculated by the
law of
mixtures.
In the course of
performing
thes
e steps, the modulus of elasticity
of carbon nanotubes of
various sizes
is calculated, as well as that of
amorphous linear p
olyethylene
. For the purpose
of the present study, comput
er simulations based
on the Molecular Dynamics method are
used. This method
is based on classical engineering and aims to interpret the macrosc
opic
p
roperties of a material through
observation of
the behavior (movements, interactions) of
its atoms. The com
putational tool
that is
used to perform
the
molecular dynamics
simulations is the open
