To
acquaint the students with the basics of nano materials, their properties and
applications.
UNIT I POLYMER CHEMISTRY 9
Introduction:
Classification of polymers – Natural and synthetic; Thermoplastic and
Thermosetting. Functionality – Degree of polymerization. Types and mechanism of
polymerization: Addition (Free Radical, cationic and anionic); condensation and
copolymerization. Properties of polymers: Tg, Tacticity, Molecular weight –
weight average, number average and polydispersity index. Techniques of
polymerization: Bulk, emulsion, solution and suspension. Preparation,
properties and uses of Nylon 6,6, and Epoxy resin.
UNIT II CHEMICAL THERMODYNAMICS 9
Terminology
of thermodynamics - Second law: Entropy - entropy change for an ideal gas,
reversible and irreversible processes; entropy of phase transitions; Clausius
inequality. Free energy and work function: Helmholtz and Gibbs free energy
functions (problems); Criteria of spontaneity; Gibbs-Helmholtz equation
(problems); Clausius-Clapeyron equation; Maxwell relations – Van‟t Hoff
isotherm and isochore(problems).
UNIT III PHOTOCHEMISTRY
AND SPECTROSCOPY 9
Photochemistry:
Laws of photochemistry - Grotthuss–Draper law, Stark–Einstein law and
Lambert-Beer Law. Quantum efficiency – determination- Photo processes -
Internal Conversion, Inter-system crossing, Fluorescence, Phosphorescence,
Chemiluminescence and Photo-sensitization. Spectroscopy: Electromagnetic
spectrum - Absorption of radiation – Electronic, Vibrational and rotational
transitions. UV-visible and IR spectroscopy – principles, instrumentation
(Block diagram only).
Phase
rule: Introduction, definition of terms with examples, One Component System- water
system - Reduced phase rule - Two Component Systems- classification –
lead-silver system, zinc-magnesium system. Alloys: Introduction- Definition-
Properties of alloys- Significance of alloying, Functions and effect of
alloying elements- Ferrous alloys- Nichrome and Stainless steel – heat
treatment of steel; Non-ferrous alloys – brass and bronze.
UNIT V NANOCHEMISTRY 9
Basics
- distinction between molecules, nanoparticles and bulk materials;
size-dependent properties. nanoparticles: nano cluster, nano rod, nanotube(CNT)
and nanowire. Synthesis: precipitation, thermolysis, hydrothermal,
solvothermal, electrodeposition, chemical vapour deposition, laser ablation;
Properties and applications
TOTAL :45 PERIODS
OUTCOMES:
The
knowledge gained on polymer chemistry, thermodynamics. spectroscopy, phase rule
and nano materials will provide a strong platform to understand the concepts on
these subjects for further learning.
