In the last decades importance of UV curable formulations has increased continuously. Their fast curing speed, solvent-free polymerization conditions, and formation hard highly crosslinked photopolymer networks represent major benefits. Commercial resins generally consist multi-functional vinyl oligomers, photoinitiators, additives, reactive diluents. Mono- diluents serve as thinners to lower o...

We propose an advanced patterned vertical alignment (PVA) mode with a fast response time through double ultraviolet (UV) exposure to UV curable reactive mesogen (RM) mixed in alignment layer. The double step UV exposures using a photomask divide an active pixel region into two regions with a modified pretilt region and a high elastics deformation energy one.

Bio-based epoxy resins are attracting widespread interest in the field of polymer thermosets as environmentally friendly building block. In present study, feasibility applying UV-curable epoxidized vegetable oils (EVOs) anti-corrosion coating is investigated. Rheological characterization EVOs carried out, and their viscosity-shear relationship evaluated. The cationic UV-curing successfully give...

The scratch resistance of coatings used on two highly visible automotive applications (automotive bodies and window glazings) were examined and reviewed. Types of damage (scratch vs. mar), the impact on customers, and the causes of scratch events were investigated. Different exterior clearcoat technologies, including UV curable and self-healing formulations were reviewed, including results from...

UV-curable polymer composites are of importance in industry, biomedical applications, scientific fields, and daily life. Outstanding physical properties of polymer composites were achieved with nanoparticles as filler, primarily in enhancing mechanical strength or barrier properties. Structure-property relationships of the resulting nanocomposites are dictated by the polymer-filler molecular ar...

The 3D printing is a combination of digital technology, material science, intelligent manufacturing and control of opto-mechatronics systems. It is called the third industrial revolution from the view of the Economist Journal. A color 3D printing machine may provide the necessary support for high value-added industrial and commercial design, architectural design, personal boutique, and 3D artis...

We have developed a package for disposable glucose sensor chips using Parylene encapsulation of a glucose oxidase solution in the liquid phase and a cover structure made of an ultraviolet (UV) curable adhesive. Parylene was directly deposited onto a small volume (1 μL) of glucose oxidase solution through chemical vapor deposition. The cover and reaction chamber were constructed on Parylene film...
