T
he biocompatible photo-curable elastic materials
were synthesized with urethane acrylate oligomer,
2-hydroxyethyl methacrylate (HEMA), and polyethylene glycol
diacrylate (PEGDA) using 2-Hydroxy-4′-(2-hydroxyethoxy)-
2-methylpropiophenone (Irgacure 2959) as an initiator. We
could obtain elastic materials with different properties such as
softness, tensile strength, and elasticity by changing the input
molar ratio of HEMA, urethane acrylate with PEGDA. Generally,
urethane oligomer with a higher PEGDA ratio has higher
elasticity and higher viscosity properties. On the other hand, as
the content ratio of HEMA increases in urethane oligomer, the
viscosity and physical properties decrease. We studied various
properties such as tensile properties, hardness, biocompatible
properties, and viscosity to find the critical point of higher
elasticity and lower viscosity according to HEMA/PEGDA ratio.
Also, the chemical structures of the synthesized polymers were
characterized using Fourier Transform Infrared spectroscopy
(FT-IR) and nuclear magnetic resonance (NMR).

Biography
Ji Eun Jang is currently a graduate student in Chungang University and
a researcher in Korea Institute of Industrial Technology (KITECH) at the
same time. Her major is integrative engineering and she is consistently
learning how to do experiments and manage novel materials. She is
currently researching biocompatible materials applied for 3D printing. In
KITECH, she held experiments regarding superabsorbent polymers and 3D
printing resins. This study aimed for innovative experimental results such
as biocompatibility and high elasticity for the application of 3D printing
materials.
