dc.description.abstract
Photopolymerization-induced phase separation presents a promising approach to enhance photopolymer
performance for additive manufacturing (AM)-related applications such as biomedical engineering, tissue
engineering, and digital dentistry. This phenomenon occurs in multicomponent systems with marginal
incompatibilities including various monomers, oligomers, and reactive diluents at the nano to microscale
levels.
The study explores a phase-separable system characterized by significant transparency changes after UV
light radiation. The system comprises isobornyl Acrylate (IBOA) diluted aliphatic urethane diacrylate
oligomer (UDA) and bisphenol-A-ethoxylate di-methacrylate monomers (Bis-EMA) photopolymerized by
the activation of Diphenyl (2,4,6-trimethylbenzoyl) phosphinoxid (TPO) as the initiator agent.
Tensile strength, impact resistance, and thermal stability were among the qualities that were quantified
before and after the system was treated to 20 wt. percent 4-Acryloylmorpholin (ACMO; Sigma-Aldrich), a
highly polar reactive diluent. Optical properties such as phase separation onset, duration, and final
transparency were assessed using a bespoke developed setup.
The research also explores the capabilities of atomic force microscopy (AFM) in characterizing
photopolymers from fracture mechanics and microstructure-property points of view. Special focus was
therefore given to the effect of sample preparation on a consistent, accurate and reliable AFM
measurement. Furthermore, to obtain a homogeneous fracture surface with minimal effects of irradiation
intensity throughout the component’s thickness, the AM process Hot Lithography was employed. The
results demonstrated the high capability of this technique in processing highly viscous formulations which
is advantageous in preparing 3D-printable photopolymers with improved toughness.
