M.Tech Project:
Studies on Fibrillation of Polytetrafluoroethylene in Polystyrene and Polymethylmethacrylate
Matrices under the supervision of Prof. Anup. K. Ghosh (IIT, Delhi), Dr. Bhabani. K Satapathy (IIT,
Delhi) and Dr. Sumanda Bandyopadhyay (GE Global Research, Innovative Plastics Program). This
work was aimed towards the understanding of the effect of networked fibril morphology of a softer
polymer on a brittle glassy polymer. The properties of interest were the mechanical, tribological,
thermal and rheological properties of the formed in situ composites. SAN coated paste extrusion
grade PTFE was used as the softer phase and both polystyrene and polymethylmethacrylate were
used as the hard glassy polymer. The desired morphology was achieved and studied by
microscopy and thermal analysis.
Project work was carried out at GE India Technology Centre, Whitefield, Bangalore.

Technical Projects:
In-Plant training for seven weeks in Berger Paints India Ltd., Howrah Factory.
B.Tech project (Four months) on “Evaluation of MBT-TMTD Binary Accelerator Systems in NR
Vulcanization” under the supervision of Dr. Bidyut B. Konar.
The aim of this work was to understand the swelling and aging behavior as well as mechanical
properties of natural rubber vulcanized with sulfur with a blend of a fast accelerator like MBT with
an ultra accelerator like TMTD. Vulcanization studies with moving die rheometer was done to see
the effect on curing time and scorch safety time.
