I especially thanked greatly Prof. R.M. Mehra, a senior member in Research and Technology Development Centre (RTDC), Sharda University for the final approval of financial support under the university R&D research funds activities. The entire received amount utilized wisely for characterization purposes. It speeded-up the whole research work.
I wish to express my sincere thanks to Prof. S.S. Islam, the director Centre for Nanoscience and Nanotechnology, Jamia Milya Islamiya University New Delhi for providing us SEM facility at relatively lower cost. I personally appreciated similar assistance received from Dr. Azad A. Khan, Technical Officer Central Instrumentation Facility (CIF) Jamia Milya Islamiya University New Delhi for the DLS measurements of my polymer samples.
