Fabricating a New Composite Material with Antimicrobial Properties


Engineers at the University of Bath, in collaboration with colleagues at the University of Ulster, have successfully manufactured a new type of ferroelectric composite material with antimicrobial properties for the first time using a revolutionary multi-material 3D printing process.

According to the researchers, using electrically responsive ferroelectric materials provides the implants with infection-fighting capabilities, making them appropriate for biomedical applications like heart valves, stents, and bone implants, lowering the risk of infection for patients.

Despite their widespread use, all biomedical implants provide some amount of risk because materials can harbor surface bio-contaminants that can cause infection. Reducing this risk may benefit patients and healthcare providers through improved results and lower costs associated with continuous therapy.

This 3D printing approach has previously been utilized by the team to create three-dimensional scaffolds for bone tissue engineering.

The breakthrough is made possible by ferroelectricity, a property of certain polar materials that generates an electrical surface charge in reaction to a change in mechanical energy or temperature. This electrical charge causes the creation of free radicals known as reactive oxygen species (ROS) in ferroelectric films and implants, which preferentially eliminate bacteria.

This is accomplished through the micro-electrolysis of water molecules on a polarised ferroelectric composite material surface.

  Simonelli undertakes research to reuse composite materials Simonelli Group is currently undertaking a research and development project to reuse composite materials, that nowadays have a vast range of uses and applications thanks to their durability and longevity, but which are also very difficult to dispose of. The De-Manufacturing research project, developed by Delta srl and Simonelli Group, is part of the Marche Region’s Marche Applied Research Laboratory for Innovative Composites (MARLIC) platform in the context of ‘Sustainable manufacturing: eco-sustainability of products and processes for new materials and de-manufacturing’. “We are truly delighted to take an active part in this virtuous synergy, promoted and developed also within the MARLIC platform as advocates of a dual objective, to make a strong contribution to the transition towards a circular economy and to grow and develop the local industrial system,” says Fabio Ceccarani, Simonelli Group Managing Director. “The De-Manu

Unsaturated polyester (UP)  resin  is a low cost thermoset with excellent processing ability and  mechanical properties  that finds applications in fiber-reinforced polymer (FRP) materials. It also crosslinks readily in the presence of a catalyst such ketone peroxide, forming an even stronger and stiffer resin. Unfortunately, this also leads to lower  fracture toughness . Several methods to enhance the toughness of the cross-linked resin have been proposed; one such method involved blending with nano-fillers m

  In the dynamic realm of materials science, polymer nanocomposites have emerged as a revolutionary class of materials with unparalleled versatility and performance. From automotive engineering to biomedical technology, polymer nanocomposites are revolutionizing industries. This article explores the potential of polymer nanocomposites, highlighting their contributions to advancing materials science and supporting a sustainable future.1 What are Polymer Nanoparticles? Polymer nanoparticles, often termed nanofillers or nanoscale additives, are integral to polymer nanocomposites, imbuing them with exceptional properties. Ranging from 1 to 100 nanometers in diameter, these nanoparticles integrate into the polymer matrix, influencing mechanical strength, thermal conductivity, and electrical resistivity. Carbon-based nanoparticles like carbon nanotubes (CNTs) and graphene reinforce polymer matrices effectively, while clay nanoparticles enhance mechanical reinforcement and flame retardancy. M
