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.
