  • An issue of major concern in the utilization of laminated composites based epoxy resin is associated with the occurrence of delaminations or interlaminar cracks, which may be related to manufacturing defects or are induced in service by low-velocity impacts. A strong interfacial filament/brittle epoxy resin bonding can, however, be combined with the high fracture toughness of weak interfacial bonding, when the filaments are arranged to have alternate sections of shear stress. To improve this drawback of the epoxy resin, UV-thermal dual curable resin were developed. This paper presents UV-thermal dual curable resin which were prepared using epoxy acrylate oligomer, photoinitiators, a thermal-curing agent and thermoset epoxy resin. The UV curing behaviors and characteristics of UV-thermal dual curable epoxy resin were investigated using Photo-DSC, DMA and FTIR-ATR spectroscopy. The mechanical properties of UV-thermal dual curable epoxy resin impregnated CF prepreg by UV curable resin content were measured with Tensile, Flextural, ILSS and Sharpy impact test. The obtained results showed that UV curable resin content improves the epoxy toughness.

  • 본 논문은 유리제 문화재 복원에 안정한 물성을 지닌 복원재료를 선정하기 위한 연구이다. 아크릴계 광경화성수지(FLGPCL04 Clear®)를 기준으로 우레탄계 광경화성수지(SECURE CP-7321®)를 10%씩 가감한 혼합 시편 11종을 제작하고 6종의 물성실험을 실시하였다. 실험결과 굴절률, 비중, 접착력, 황변도의 측정값에 대해서는 11종 혼합재료 모두에 대하여 유사하였으나 표면경도 및 압축강도 측정값에서는 우레탄계 광경화성 수지의 혼합 비율이 10~20% 범위일 때 가장 적합하였다. 즉, 유리제 유물을 복원한 이후의 상태 유지에 가장 효과적이다. 이와 같은 연구결과를 바탕으로 아크릴계와 우레탄계 광경화성 수지를 9:1로 혼합한 재료(AU9010)를 경주 황남대총 북분에서 출토된 유리잔 (황북519)의 보존 처리에 적용하였다.

  • UV-curable resin has the properties of quick-drying, thigh productivity at low temperature, energy savint, space saving, solventless, non-polluting and low-stinking, and thus, UV-curing system has been widely used in the fields of printing inks, adhesives, paints and coating agents. This study has been executed to micro-patterning used UV-curable resin, The micro-patterning properties of this photoresist were investigated under irradiation of UV light low pressure mercury lamp. When the exposed photoresist film was developed by pure water developer, the resolution of this photoresist was about 50$\mu\textrm{m}$.

  • UV-curable resins have adventages of quick set, space saving, clean environment, and efficient use of energy. The polymerization induced phase separation has been studied to solve the problem in UV-curing of thick films and develop the new functional materials. On the exposure to UV irradiation, the dynamic elasticity properties were mesured for mixtures of alkyd resin and UV-cruable monomers which have different molecular structures and molecular weights. The curing rate increases with increasing temperature and UV intensity. In addition, The gel point is strongly influenced by temperature and UV intensity

  • The ultraviolet(UV)-curable materials are widely used in inks and coatings. In this paper is designed to develop materials having flexibility and functionality with UV-curable acrylate monomer and alkyd resin. At first, phase diagram is prepared for miscibility of UV -curable acrylate monomer with alkyd resin. Also the gel fraction and dynamic viscosity are measured to curing speed of mixing system. In results, it has been demonstrated that miscibility and curing speed are greatly influenced by alkyd resin content.

  • The UV nanoimprint technology uses the UV light as the energy source. Because the imprint process is carried out in room temperature and low pressure, this technology has its own merits compared to the thermal nanoimprint. However, in UV nanoimprint technology, a resin which has low viscosity is essential for the improvement of accuracy. In this research, a resin (named as IMS01) which has relatively low viscosity was developed. And a measurement system was developed in order to measure the degree of cure of the resin. The measurement system which is composed of FT-IR, UV light source and optical guide can measure the degree of cure in real time. From the experimental results, it was found that the IMS01 is cured more rapidly than existing resin (PAK01).

  • UV-curable resin has the properties of quick-drying, high productivity at low temperature, energy, space saving, solventless, non-polluting and low-stinking, and thus, UV-curing system has been widely used in the fields of printing inks, adhesives, paints and coating agents. This study has been executed to develop a new functionnal material by the polymerization induced phase separation. The results obtained were as follows. As for the curing properties of the monomer/prepolymer/alkyd resin blends, it was found out that there was a peak by the polymerization induced phase separation when measuring the changes of viscosity and elasticity. It was also found out that such polymerization phase separation occurred in case that the alkyd resin contents were 20wt% and 30wt% and not found at the contents of 40wt%. Therefore, it would be desirable to maintain the contents of alkyd resin at less than 30wt% in order to use the polymerization induced phase separation.

  • Antimony doped tin oxide (ATO) nanoparticles were added as nanofillers to UV-curable polyester-acrylate (PEA) resin for coating to improve thermal, mechanical, and electrical properties. In this study, ATO nanoparticles were grafted by 3-glycidyloxypropyltrimethoxysilane and 3-methacryloxypropyltrimethoxysilane respectively to improve dispersion and interfacial adhesion. The physical properties and surface scratch hardness of the UV-curable nanocomposite coating were improved considerably by introducing the modified ATO nanoparticles.
