Single-Polymer Composites

This book discusses the concept of single polymer composites (SPCs), their preparation, and properties and the main factors which affect the manufacturing of this class of composites. It deals with the leading classes of polymers, chapter wise, which have been majorly explored for manufacturing SPCs - polyolefins, polyesters, polyamides, and LCPs - includes a case study on manufacturing of SPCs, and devotes three chapters to detailed analyses of research on all-cellulose composites. Addressing the concerns of the researchers, it also answers intriguing questions in the field of SPCs with pointers to the right references. Key Features

• Presents a summary of single polymer composites based on various polymers

• Includes mechanical and thermal properties of single polymer composites

• Reviews detailed view of eco-friendly approaches to composites

• Offers a special focus on all-cellulose composites

He is involved in projects with joint funding from industry and Government of India for developing practical solutions for industry under the Uchhatar Abhiskar Yojana (UAY).

He has been working with single polymer composites for the last two decades. Part of his Phd work was using polypropylene filaments in single polymer composites. He was the Principal Investigator of a project sponsored by GAIL, Government of India, on development of high impact structures from single-polymer composites from HDPE. The project was successfully executed and has been funded for second stage of execution jointly with Indian Institute of Packaging, Government of India for developing prototypes. He has also worked on all-cellulose composites systems jointly with the co-author.

Bapan Adak obtained B.Tech degree in 2010 from Govt. College of Engineering and Textile Technology, Serampore (West Bengal, India) in Textile Engineering. During his B.Tech, he worked on 'Dyeing of silk with natural coloring matters with or without mordants' and published his work in a reputed textile journal. In 2010, he joined in Arvind Ltd, Gujarat, India and continued his work for three years as manufacturing manager. In 2013, he started M.Tech in Fibre Science and Technology from Department of Textile Technology, Indian Institute of Technology Delhi, India and received his M.Tech degree in 2015. During M.Tech, he worked on cellulose based single-polymer composites popularly termed as - 'All-cellulose composites'. He has published several papers in reputed journals from his M.Tech research work. Currently, he is doing Ph.D from Department of Textile Technology, Indian Institute of Technology Delhi, India. His PhD topic is related to 'Studies on high gas barrier and weather resistant polyurethane nanocomposite films and laminates', which is a part of an ongoing project sponsored by Aerial Delivery Research & Development Establishment (ADRDE, Agra), Defence Research and Development Organization (DRDO, India).
