ABSTRACT
Designing
multifunctional
composites
with
high
flame
retardancy
and
excellent
electromagnetic
shielding
performance
is
of
significant
importance.
In
order
to
address
the
poor
retardant
performances
thermoplastic
polyurethane
(TPU)
composites,
in
this
work,
γ‐propyl‐trimethoxysilane
(KH550)
functionalized
silicon
microencapsulated
ammonium
polyphosphate
(SiAPP‐NH
2
)
was
synthesized
using
interface
modulation
technology.
Then,
SiAPP‐NH
combined
a
copper
metal–organic
framework
(MOF‐Cu)
through
microencapsulation
electrostatic
self‐assembly
techniques
prepare
retardants
@MOF‐Cu).
Subsequently,
TPU
were
prepared
melt
blending
@MOF‐Cu
material.
The
results
showed
that
interaction
between
matrix
significantly
enhanced.
Compared
pure
TPU,
TPU/5SAN@1MC
composite
exhibited
decreases
78.7%,
51.3%,
59.3%,
58.7%
peak
heat
release
rate,
total
release,
smoke
carbon
dioxide
respectively.
addition,
TPU/1SAN@1MC/rGO
achieved
an
average
effectiveness
13.82
dB
X‐band,
enabling
its
broad
commercial
application.
This
study
offers
promising
strategy
for
fabrication
good
properties.
