Nanocomposite coating – paint & varnish
Modification of epoxy resins is still necessary since some application in the
engineering area require higher mechanical and thermal properties.
Different types of nanoparticles such as graphite nanofiber, carbon nanotubes,
nanoclays, cellulose nanofiber, and nanoalumina have been utilized to enhance the
epoxy resin properties.

Activities
POLYMERS:
TEC STAR customizes and produces nanoparticles that, used as nanofillers in place of traditional fillers, are
able to intercalate and bond to the polymer chains, as a consequence of their typical nanometric dimension
and huge specific surface. In this way it is possible to tune different properties (mechanical, electrical,
magnetic, flame resistance, etc.) with filler concentration within the matrix not larger than 2-5% wt. and
with no variation of material workability.
Polymers treated:
. Polypropylene
. Polyurethane
. PMMA
. PEEK

Example
Problem: to improve the impact resistance of a thermoplastic polymer, obtained by injection
molding.
Activity:
a) characterization of the molded part:
• Mechanical properties (tensile test – ISO 527; bending test – ISO 178; impact test – ISO
180, Vicat – ISO 306, HDT – ISO 75, MFI – ISO 1133)
• SEM/Focused Ion Beam – to check the nanoparticles distribution inside the polymer
b) production of real parts using injection molding, starting from
nanocomposite masterbatches.
