Modulation of the lower critical solution temperature of thermoresponsive poly(N-vinylcaptrolactam) utlizing hydrophilic and hydrophobic monomers
Halligan, Elaine; Zhuo, Shuo; Colbert, Declan Mary; Alsaadi, Mohamad; Tie, Billy Shu Hieng; Bezerra, Gilberto S.N.; Keane, Gavin; Geever, Luke M. (MDPI, 2023-03-23)Four-dimensional printing is primarily based on the concept of 3D printing technology. However, it requires additional stimulus and stimulus-responsive materials. Poly-N-vinylcaprolactam is a temperature-sensitive polymer. ... -
Post-process considerations for photopolymer 3D-printed injection moulded insert tooling applications
Keane, Gavin; Healy, Andrew V.; Devine, Declan M. (MDPI, 2024-04-17)Injection moulding (IM) is a manufacturing technique used to produce intricately detailed plastic components with various surface finishes, enabling the production of high-tolerance functional parts at scale. Conversely, ... -
Synthesis and characterisation of hydrogels based on poly (N-vinylcaprolactam) with diethylene glycol diacrylate
Halligan, Elaine; Tie, Billy Shu Hieng; Colbert, Declan Mary; Alsaadi, Mohamad; Zhuo, Shuo; Keane, Gavin; Geever, Luke M. (MDPI, 2023-05)Poly (N-vinylcaprolactam) is a polymer that is biocompatible, water-soluble, thermally sensitive, non-toxic, and nonionic. In this study, the preparation of hydrogels based on Poly (N-vinylcaprolactam) with diethylene ... -
Synthesis and characterization of 4D-printed NVCL-coDEGDA resin using stereolithography 3D printing
Halligan, Elaine; Tie, Billy Shu Hieng; Colbert, Declan Mary; Alsaadi, Mohamad; Zhou, Shuo; Keane, Gavin; Geever, Luke M. (MDPI, 2024-03-19)The design and manufacturing of objects in various industries have been fundamentally altered by the introduction of D-dimensional (3D) and four-dimensional (4D) printing technologies. Four-dimensional printing, a ... -
Synthesis of NVCL-NIPAM hydrogels using PEGMA as a chemical crosslinker for controlled swelling behaviours in potential shapeshifting applications
Tie, Bill Shu Hieng; Halligan, Elaine; Zhuo, Shuo; Keane, Gavin; Geever, Luke (MDPI, 2023-03-20)Stimuli-responsive hydrogels have recently gained interest within shapeshifting applications due to their capabilities to expand in water and their altering swelling properties when triggered by stimuli, such as pH and ...
