Isobornyl acrylate (IBOA) is utilized as a reactive monomer to significantly enhance the performance of UV-curable waterborne polyurethane (WPU) films. In this study, IBOA was incorporated alongside methyl methacrylate (MMA) and pentaerythritol triacrylate (PETA) into a commercial WPU emulsion, forming an IBOA-modified WPU system (IAWPU).
The rigid cyclic structure of IBOA plays a critical role in increasing crosslinking density and restricting polymer chain mobility during UV curing. As a result, the viscosity of the IAWPU emulsion decreased, while particle size increased, and the emulsion remained stable for over six months. Upon UV curing (365 nm, 1000 W), IAWPU films exhibited remarkable improvements in physical properties.
Compared to pure WPU, the IAWPU film demonstrated a dramatic increase in tensile strength-reaching up to 13.52 MPa, 14 times higher than that of unmodified WPU. Additionally, the incorporation of IBOA enhanced water resistance, as evidenced by a higher contact angle and lower water absorption. These properties are attributed to both the hydrophobic nature and structural rigidity of IBOA.
This work confirms that IBOA is a highly effective functional monomer for formulating high-performance UV-curable WPU films, offering a promising route for advanced coatings with superior mechanical strength and durability in moisture-rich environments.

Isobornyl acrylate (IBOA) plays a pivotal role in the preparation of high-performance organogels with enhanced environmental tolerance for flexible electronic applications. In this study, IBOA was combined with N-hydroxymethylacrylamide (NMA) and 2-hydroxyethyl acrylate (HEA) in a dimethyl sulfoxide (DMSO) medium to synthesize a multifunctional IBOA-NMA-HEA organogel via UV-induced free radical polymerization.
The incorporation of IBOA, a hydrophobic monomer with a rigid cyclic structure, significantly improves the organogel's anti-swelling, anti-freezing, and anti-drying properties. These characteristics enable the organogel to maintain mechanical integrity and sensing performance in extreme conditions, including sub-zero temperatures and aquatic environments such as pure water, seawater, and alkaline solutions. The resulting material exhibits stable performance for up to 15 days under such conditions.
Mechanically, the organogel demonstrates excellent flexibility, a broad strain range, and rapid, cyclically stable response characteristics, making it an ideal candidate for strain sensors. These sensors successfully monitor human motion and marine animal activities across diverse environments, ensuring real-time, precise data capture.
This work showcases the critical function of isobornyl acrylate in engineering organogels with superior environmental resilience, offering a straightforward and scalable strategy to expand the utility of organogel-based flexible electronics in harsh and dynamic settings.

Isobornyl acrylate (IBOA) serves as a key monomer in the formulation of photo-curable resins for digital light processing (DLP) 3D printing, enabling the development of mechanically tunable materials. In this study, IBOA was combined with poly(ethylene glycol) diacrylate (PEGDA) and reactive oligomers synthesized from 2-ethylhexyl methacrylate (PEHMA) and poly(ethylene glycol) methacrylate (PEGMA). These oligomers were prepared via catalytic chain transfer polymerization (CCTP) and subsequent addition-fragmentation chain transfer (AFCT) polymerization, and incorporated into the IBOA-based resin as polymerizable additives.
The incorporation of PEHMA and PEGMA reactive oligomers profoundly influenced the mechanical performance of the printed parts. PEHMA-oligomers acted as plasticizers within the IBOA matrix, leading to a significant reduction in tensile strength and elongation, indicative of material softening. In contrast, PEGMA-oligomers induced a transition from brittle to ductile, elastomer-like behavior due to phase separation between the polar PEG segments and the hydrophobic IBOA matrix.
These findings demonstrate that IBOA enables compatibility with functional oligomers to tailor resin properties, allowing precise control over stiffness, elasticity, and toughness in 3D printed components. This approach offers a facile and scalable strategy to design custom DLP resins with only minor additive content (≤10 wt%), expanding the utility of IBOA-based systems in advanced additive manufacturing.
