smart polymers make life easy and comfortable in future

1. Smart Polymers
future as biomaterials
• Polymer that change in
response to environmental
changes are called smart
polymers
• Piezoelectric Materials
• Thermoresponsive
Materials
• Shape Memory Alloys
• Polychromic,
Chromogenic or
Halochromic Materials

2. Piezoelectric Materials
• The piezoelectric effect is
generally thought to act as
a biological force sensor.
• Piezoelectric materials
either produce a voltage
when stressed or alter
shape under the influence
of an electric charge.
• Piezoelectric materials are
used in electromechanical
devices.

3. Thermoresponsive Materials
• Change shape under influence
of temperature
• materials alter their shape
under the influence of the
ambient temperature
• Used in cancer therapy to
identify tumours.
• Used in drug delivery and
killing of tumour by
MNP(MICROGEL
NANOPARTICLES)

4. Magnetic Shape Memory Alloys
• Changes in shape due to change
in magnetic field
• Regains original shape when
heat is applied
• Mainly used to reconstruct
broken bones
• Aircraft ,pipelines ,magic shows
(shape shifting) _, robots
,surgery , medicine etc.,

5. Polychromic, Chromogenic or
Halochromic Materials
• Change color based on
external stimuli .i.e., pH,
temp. light ,electricity.
• Light-photochromic ,
• Temp-thermochromic
• pH-halochromic

6. Applications
• Specifically targeted drug
delivery in surgery by
forming a micelle with
hydrophobic and
hydrophilic substances.
• Plasters (band aids) that
lose their stickiness when
you want to take them off
so don’t rip your skin off.

7. • Biodegradable plastic bags.
• non-stick chewing gum (Rev 7)
• Even biological uses like detecting blood
glucose
• Levels triggering the release of insulin.
• Smart polymers are used to change colour in
light widely used in sunglasses and computers

8. • Used as screen in touch phones.
• Used as PZT in heart to generate energy
• Used to prepare a shirt
• Piezo electric products materials for
actuator, oscillator and sputtering target.
• Used in seed coatings

9. • Used in breakage bones
