Macromolecular barcoding for tracing plastic materials for the circular economy – a game changer for recycling

Plastic waste reduction and management is perhaps the most critical challenge facing modern economies, and plastic pollution cannot be resolved by generic approaches to research or to problem-solving.QUT's Soft Matter Materials Team aims to resolve the anonymity and ubiquity of plastics by pioneering a simple optical readout system that can identify the uniquely coded information in macromolecules that have been embedded in plastics.You will be part of this dynamic team led by ARC Laureate Fellow, Christopher Barner-Kowollik, from QUT’s Centre …

Fighting slime with nitroxides and polymers

Biofilms, more commonly recognised as slime, are complex communities of microorganisms, which provide these creatures with a niche where they are able to flourish in conditions where they might not normally survive.Because of this enhanced survivability, bacterial biofilms show enhanced resistance to disinfectant and antibiotic treatment, and are the cause of nearly three quarters of hospital-acquired infections. Nitroxides, molecules that possess a stabilised free radical, are able to disperse these biofilms and make them susceptible to treatment.Our research group is …

Research and development of novel building materials using Australian natural minerals

This project will explore the potentials of local natural minerals and waste products for developing next-generation, high-quality precast panels that impose a high cost environmental footprint.Our research will:advance fundamental knowledge of natural mineralsreduce building industry dependence on lower-quality imported productsexpedite local manufacturing of energy efficient solutions for building facades, roofs and wall systems.Use of precast panels speeds up construction, reduces on site defects, construction times, scaffolding and site labour costs. These advantages contribute to increased productivity in the building industry. …

Geopolymers

Geopolymers are materials which are rapidly finding interest in industry because they are 90% less polluting than conventional portland cement. They're made by reacting aluminosilicate materials with alkaline solutions in the presence of a reaction promoter.We're examining new geopolymers made from Australian-based minerals, such as zeolites and clays.

Programming polymers

Radical polymerisations play a key role in both commercial and fundamental research with it being in 45% of international polymer production at 100 million tons per year.However, radical polymerisations still suffer from synthetic drawbacks, such as all-carbon polymer backbones, which prevent their (bio)degradability.In this project, we'll develop novel polymers which can be programmed towards controlled degradability.Towards this goal, you'll develop a polymerisation technique that allows to incorporate small natural building blocks (i.e. peptides) into synthetic polymers. These peptide sequences will …

Highly fluorescent and brighter emitters for next generation flexible OLEDs and displays

Display devices are composed of an array of organic light emitting diodes (OLED) in the form of pixels (red, blue, green). Such devices are present in various electronic appliances, including:mobile phonestabletstelevisionssmart packaging productswearable productsautomobile dashing boards.Currently, inorganic light emitting diodes (LEDs) control the display market, but this technology has some limitations such as:high fabrication costlarger area processinglimited to rigid products.The next generation of devices are expected to be flexible and stretchable so they can be used for future rollable televisions …

Finite element methods for modelling the deformation of polymers

The finite element method (FEM) is by now a well-established and widely accepted approach for modelling the deformation of linearly elastic materials.In this project we will explore which FEM approach and constitutive laws may be applicable for modelling polymers, which have more deformation behaviour than a simple elastic material. Our long-term goal is to be able to accurately model the deformation of polymer bioscaffolds fabricated with the novel melt-electrowriting (MEW) additive manufacturing process. …

Polymer particles as precision sensors for molecules

Polymer particles are a billion-dollar industry with a diverse range of applications from biomedical to industrial coatings.As a prime example, point-of-care testing devices rely on polymeric particles with various size and functionality to conveniently allow instantaneous, selective, and precise diagnostics.However, as new applications arise and current applications advance, these demand the preparation of increasingly complex material and particle systems.The Soft Matter Materials Team has developed a simple method to form uniform particles without any additives, initiators or stabilisers.The ambient temperature …

Biological engineering of waste into functional fungal mycelial composites and leather

Numerous residues from agriculture and the urban lifestyle comprise of carbon polymeric chains that are accessible to fungi. Fungi grow on and within these structures and can generate a bound matrix that has notably different properties.This project aims to take a waste material and repurpose it using fungal mycelial mats to penetrate and bind the organic compounds. These can be used directly as packing material or internal building materials.The project will also strive to generate aerial mycelia, which will be …

Controlling soft matter materials at the nano-level – how to construct materials whose mechanical properties can be remotely adjusted

Nature is an expert at developing high-performance materials which combine properties like high toughness, stiffness, and low weight.Some well-known examples include:woodbonespider silk.In this project we aim to mimic the structure and properties of another, less known natural high-performance material: nacre.Additionally, we want to introduce a light-adaptive control mechanism. This will enable a controlled transformation of physical and mechanical properties in real-time.To achieve adaptable properties, a control mechanism on the molecular level is required, featuring several distinct functional plateaus.It is proposed …
