OBJECTIVES:
•    To make the students conversant with basics of polymer chemistry.
To make the student acquire sound knowledge of second law of thermodynamics and second law based derivations of importance in engineering applications in all disciplines.
To  acquaint  the  student  with  concepts  of  important  photophysical  and  photochemical processes and spectroscopy.
To develop an understanding of the basic concepts of phase rule and its applications to single and two component systems and appreciate the purpose and significance of alloys.
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).

UNIT  IV        PHASE RULE AND ALLOYS                                                                                   9
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, electrode position, chemical vapour deposition, laser ablation; Properties and applications.

OUTCOMES:

TOTAL :45 PERIODS
