Biomedical Applications of Elastomers
Organised by the IOM3 Rubber in Engineering Group in conjunction with the Biomedical Applications Division
The afternoon technical discussion meeting (ATDM) examined the behaviour of elastomers that are used in biomedical applications. This event was organised jointly with the Biomedical Applications Division of the IOM3. Click on the title of the talk to download a PDF of the presentation.

Introduction - Prof James Busfield
Silicone elastomers: from fast curing chemistry to biomedical applications (3.0MB) - Khai Duong Quang Nguyen, William Megone, Dexu Kong and Julien Gautrot (QMUL)
The possibility of systematically tailoring the mechanical properties of silicone network whilst manipulating their surface functionalities via thiol-ene chemistry provides attractive features for a range of applications including 3D printing, microfabrication, hydrogel-embedded microfluidic systems and cell culture.
The effects of sterilisation on properties of platinum cured silicone tube (1.3MB) - Beckie Govier (Watson-Marlow Tubing)
Precision peristaltic tubing is manufactured in an ISO 14644-1 Class 7 clean room for use in biotechnology and pharmaceutical manufacturing processes. This talk discussed the effects of sterilisation on critical performance parameters.
Soft and Small - the challenges of compression testing hydrogel embolic beads - Rosemary Bushby and Andy Lewis (Biocompatibles UK, BTG)
Nano-indentation single bead compression tests on small (<300 µm) hydrogel embolic beads can characterise compression modulus and show complex mechanical responses due to time dependent phenomena.
Synchrotron X-ray studies of elastomers used in biomedical applications under strain (24.6MB) - Tan Sui (University of Surrey)
In situ synchrotron X-ray techniques combined with modelling provide an opportunity to obtain insights into the relationship between the structure and function of polymeric materials from multi-scale perspective. Examples presented included thermoplastic polyurethane (TPU) elastomers in which the internal strain evolution, origins of Mullins effect and temperature-dependent changes within the materials depends on the length-scale of consideration.
Increasing the X-ray contrast of polyethylene (1.8MB) - Elise Pegg (Bath University)
Due to the typically low X-Ray attenuation of polymers, polymeric medical implants can be difficult to visualise using X-ray based imaging methods. This talk examined different techniques to increase the X-ray contrast of polymers, with a particular focus on polyethylene.
Use of platinum cured silicone for increased comfort, control and moisture management in prosthetics (2.6MB) - Ana Gallego (Blatchford Group)
Laser drilled prosthetic liners manufactured in platinum cured silicones and silicone-based coatings can achieve a reduction in sweating, increased comfort and control of the prosthesis. This talk depicts the anatomy of a sweat management prosthetic liner and the benefit for amputees.
