Senior Research Associate in 4D Printing of Liquid-Crystal Elastomers

Overview

The role supports the Principal Investigator (Dr Rainer Groh) in delivering an ambitious UKRI Future Leaders Fellowship research programme. By leveraging shear alignment in Direct Ink Writing, the role will tailor the spatial distribution of nematic directors in Liquid Crystal Elastomers (LCEs) to morph 2D printed geometries into target 3D shapes under various stimuli. An additional area of novelty is investigating how short carbon fibres can reinforce LCEs and how fibre directionality interacts with nematic directors.

The role requires an experienced researcher and specialist in soft matter and 3D/4D printing. In addition to additive manufacturing and material characterisation, the role holder should be comfortable with analytical/computational modelling to rationalise experiments. Contributions of ideas and methodological enhancements to guarantee successful delivery of the project are expected. Outcomes should be communicated in premier journals and conferences in soft matter, smart materials and additive manufacturing.

Where practical, the role holder may contribute to teaching through co-supervision of PhD students and teaching support for the PIs final-year unit Mechanics of Lightweight and Composite Structures. Training in effective communication, leadership and entrepreneurship will be available through the PIuture Leadership Fellowship to prepare the role holder for greater responsibilities in the future.

What will you be doing?

The role holder will:

• Establish a 3D/4D printing laboratory based on a DIW printer
• Print LCEs with spatially tailored nematic directors with the printed structures able to morph between a flat geometry and a target 3D shape
• Devise new ways of reinforcing LCEs with recycled carbon fibres to enhance mechanical properties and demonstrate new morphing capabilities
• Characterise and test the printed structures at the University of Bristol and project partners
• Implement or use computational software that predicts, rationalises and designs targeted distributions of nematic directors/fibre orientations to produce a target 3D shape

You should apply if

• You are excited by working at the interface of morphing soft matter, computational design and automated manufacturing
• You have a strong background in soft matter mechanics
• You have experience in 3D/4D printing of soft matter materials and particularly liquid crystal elastomers
• You are excited by starting a new capability in a world-leading research lab
• You have a desire to explore real-world impact of your research
