Natural polymers like cellulose, chitin, chitosan, alginate are one of the most abundant and renewable polymer with robust mechanical properties. However large scale utilization of cellulose/chitin/chitosan has not been possible because it leaves a large environmental footprint due to the hazardous solvents used during its extraction/processing. Also, cellulose/chitin/chitosan fibres have traditionally been used for mono-functional task such as a material for designing textiles. Read more Read less
The main focus of the proposed research project is to develop multifunctional (electrically conducting) and high performance biopolymer textiles. We have developed an environmentally benign method for manufacturing of cellulose fibres using ionic liquid as a “green” solvent [Rahatekar et al, Polymer, 2010; Zhu et al, ACS Sustainable Chemistry and Engineering, 2016; Singh et al, Nanoscale, 2017]. Ionic liquids can act as solvent to dissolve conducting polymer such as polyaniline. As a part of this project, we aim to use ionic liquids as a common solvent for dissolving biopolymer (such as cellulose) and polyaniline to produce electrically conducting textile fibres using wet spinning and electrospinning process. Such a textile fibre can be used in a smart shirt which can measure the body temperature and heart rate of a patient or as a soft biocompatible electrode for stimulation of neurons. We will also explore adding natural products such as curcumin (extract from turmeric) which is shown to be effective in antimicrobial and anti-cancerous properties to develop bandage for anti-microbial and potentially help increase the immune response for fighting cancerous cells.
What will you learn during MSc by Research (MSc Training)?
The student will learn the following techniques/skills:
• Natural polymer Textiles manufacturing, fibre manufacturing and surface modification
• Mechanical testing of the textiles to test its performance under stress; electrical conductivity and other functional properties of fibres
• Textiles for antimicrobial, tissue engineering and other biomedical applications
We will work in collaboration with Cambridge Nanosystems (Dr Jinhu Chen), which is a world leading high quality, high performance graphene and nanoparticles synthesis and its industrial applications in engineering sectors. The nanoparticles will be used to reinforce the cellulose and natural polymer fibres to achieve high electrical conductivity and superior mechanical properties of the fibres.
Future Job prospects:
The fibres manufacturing methods will be useful for range of relevant industries working in textiles manufacturing like Du Pont, USA and Europe; Lenzing in Europe, Sappi in South Africa, Rayonier in USA and Australia/New Zealand; Birla Textiles in India; Fulida Group, Sateri Viscose, Sanyou Chemicals, and Yamei Fibres in China; Daicel corporation in Japan.

The student needs to support the MSc by Research tuition fees (£9,000/year for UK or EU student, and £18,500/year for overseas students) and the living expenses (approximately £800-£1000 per month). The cost for running the composites manufacturing and testing experiments and facilities cost will be supported by the Enhanced Composite and Structures Centre at Cranfield.
Cranfield Doctoral Network
Research students at Cranfield benefit from being part of a dynamic, focused and professional study environment and all become valued members of the Cranfield Doctoral Network. This network brings together both research students and staff, providing a platform for our researchers to share ideas and collaborate in a multi-disciplinary environment. It aims to encourage an effective and vibrant research culture, founded upon the diversity of activities and knowledge. A tailored programme of seminars and events, alongside our Doctoral Researchers Core Development programme (transferable skills training), provide those studying a research degree with a wealth of social and networking opportunities.
