3D printed polymers are less stable than injection moulded counterparts when exposed to terminal sterilization processes using novel vaporized hydrogen peroxide and electron beam processes.
Chen, Yuanyuan; Neff, Martin; McEvoy, Brian; Cao, Zhi; Pezzoli, Romina; Murphy, Alan; Gately, Noel; Hopkins Jnr, Michael; Rowan, Neil J.; Devine, Declan M. (Elsevier, 2019-11-21)There is an increasing trend for use of 3D printing processes in healthcare due in part to emergence of customised medical devices and associated low manufacturing cost. However, there is a dearth of knowledge on the ... -
Analysis of the mechanical properties of solvent cast blends of PLA/PCL.
Chen, Yuanyuan; Geever, Luke M.; Higginbotham, Clement L.; Devine, Declan M. (Trans Tech Publications, 2014-09)Polylactic acid (PLA) is the most promising material in the biodegradable category. However, brittleness and poor thermal stability restrict its application. To overcome this limitation, PLA may be blended with other ... -
Composite films of thermoplastic starch and CaC12 extracted from eggshells for extendiing food shelf-life
Araujo, Jeovan A.; Cortese, Yvonne J.; Mojicevic, Marija; Fournet, Margaret Brennan; Chen, Yuanyuan (MDPI, 2021-09-03)Calcium chloride (CaCl2) has been widely used to maintain the quality of fresh-cut fruits and vegetables because it stabilizes and strengthens the membrane system against fungal attacks. It is mainly applied via spray ... -
Granule-based material extrusion is comparable to filament-based material extrusion in terms of mechanical performances of printed PLA parts: a comprehensive investigation
Liu, Handai; Gong, Ke; Portela, Alexandre; Cao, Zhi; Dunbar, Ronan; Chen, Yuanyuan (Elsevier, 2023-08-05)To implement a circular economic life for thermoplastic waste, such as polylactic acid (PLA) waste from filament-based material extrusion (FME) printing and reduce the costs associated with producing filaments for the FME ... -
Halloysite nanotube reinforced polylactic acid composite.
Chen, Yuanyuan; Geever, Luke M.; Killion, John; Lyons, John G.; Higginbotham, Clement L. (Wiley, 2017-10)Polylactic acid (PLA) has long history in medical applications, and reinforced PLA has the potential to be used in the medical applications that require high mechanical strength such as coronary stents and bone fixation ... -
Influence of extrusion screw speed on the properties of halloysite nanotube impregnated polylactic acid nanocomposites
Venkatesh, Chaitra; Chen, Yuanyuan; Cao, Zhi; Brennan, Shnae; Major, Ian; Lyons, John G.; Devine, Declan M. (De Gruyter, 2021)Poly (lactic acid)/halloysite nanotube (PLA/HNT) nanocomposites have been studiedextensively over the past fewyears owing to the interesting properties of the polymer, PLA, and the nanoclay, HNT, individually and as ... -
Macro and micro routes to high performance bioplastics: bioplastic biodegradability and mechanical and barrier properties
Attallah, Olivia A.; Mojicevic, Marija; Garcia, Eduardo Lanzagorta; Azeem, Muhammad; Chen, Yuanyuan; Asmawi, Shumayl; Fournet, Margaret Brennan (MDPI, 2021-06-30): On a score sheet for plastics, bioplastics have a medium score for combined mechanical performance and a high score for biodegradability with respect to counterpart petroleum-based plastics. Analysis quickly confirms ... -
Reinforced polylactic acid for use in high strength biodegradable medical implants.
Chen, Yuanyuan; Geever, Luke; Higginbotham, Clement L.; Killion, John; Lyons, John; Devine, Declan M. (2016)Traditional medical implants, such as orthopedic screws, pins, and coronary stents, are almost exclusively metallic due to high mechanical strength requirements. However, issues related to the use of permanent metallic ... -
Review of multifarious applications of Poly (lactic acid)
Chen, Yuanyuan; Geever, Luke M.; Killion, John A.; Lyons, John G.; Higginbotham, Clement L. (Taylor & Francis, 2016)Poly (lactic acid) is considered to be a promising alternative to petroleum-based polymers due to its renewability, biodegradability, biocompatibility, and good mechanical properties. Because of the high cost, the applications ... -
Surface modified halloysite nanotubes reinforced polylactic acid for use in biodegradable coronary stents.
Chen, Yuanyuan; Murphy, Alan; Scholz, Dimitri; Geever, Luke M.; Lyons, John G.; Devine, Declan M. (Wiley, 2019-08)Poly(lactic acid) (PLA) was reinforced halloysite nanotubes (HNTs) in this study. To improve dispersion and interfacial adhesion of HNTs within the PLA matrix, HNTs were surface modified with 3‐aminopropyltriethoxysilane ...
