In 2000s, the interest of ROHAS has been increased and the environmental problem has begun to be discussed as the environmental and global value, not the individual perspective. And the standard of value for eco-friendly awareness has been expanded to the economic category. The trend of eco-friendly fabric can be divided into 3 periods depending on the property. The period for natural fabric with visual effects(2002~2004) can be summarized as the creation of natural shape using the natural image, the interaction of cotton and the technology from the visual perspective. In the period of functional conjunction with eco-friendliness and technology(2005~2008), the eco-friendly awareness through the conjunction of technology and nature and the re-cycling, and the responsibility to the environment had been increased. In the period of sustainable development for nature and environment(2009~2011), it showed the conjunction with nature and the integration with technology and eco-friendly issues. Therefore, the characteristic of eco-friendly trend in fabric since 2000 can be said; firstly, the high-quality fabric has been developed with technological development for the functional progress. Secondly, the ethical creativity has been displayed with the development and utilization of eco-friendly recycling materials. Thirdly, the materials reflected with eco-friendly issues have emerged.

Recently, global facing environmental issues have been raised caused by plastic waste. Hence, increasing the demand for interest in environmentally friendly materials. In this row, research on engineering composite materials also replacing the synthetic reinforcement by introducing natural fibers. However, focus on the strength and interfacial adhesion between matrix and reinforcement is very essential in natural fiber composite, which is insufficient in the literature. There are number of approaches for improving the mechanical strength of the composites, one of the common methods is to reinforce additive nanoparticles. The present investigation, bio-additives were synthesized utilizing bio-waste, cheap, bio-degradable sea-weed powder that could replace expensive nanomaterials and reinforced into the CFRP composite through Hand lay-up followed by a vacuum process. Mechanical properties were evaluated and analyzed through microanalysis. The results concluded that synthesized additives are effective for improving mechanical properties such as tensile, flexural, impact, and shear strength. Overall, the results confirmed that the fabricated composites have potential applications in the field of engineering applications.

광촉매능을 갖는 $TiO_2$는 국내외적으로 많은 연구가 진행되고 있으며, 빛의 조사로 발생하는 다양한 물리 화학적 촉매특성이 환경정화뿐만 아니라 및 에너지 흡수차단 기능도 갖고 있어 최근 주목을 받고 있다. 본 연구에서는 친수성을 가지는 친환경 창호소재용 및 초친수성을 가지는 자동차의 사이드미러 개발을 위해 유리표면에 이종밴드갭을 갖는 복합구조 $TiO_2/Cr_2O_3/Cr$ 박막을 스퍼터링법으로 증착하여 중간층인 $Cr_2O_3$의 역할을 고찰하였다. Cr, 결정질 $Cr_2O_3$ 기판의 경우 Anatase상과 Rutile상이 공존하는 미세조직이 관찰 되었으며 비정질 $Cr_2O_3$ 기판의 경우는 균일한 결정질 anatase-$TiO_2$상이 나타났다.

Recently, sea algae cultivation as carbon sink and carbon dioxide fixation have been considered. Also, various researches on bioenergy derived from sea algae and the utilization of fibers, saccharide, and lipid of sea algae have been performing. Till now, algae fibers has been used for manufacturing of paper and reinforcing of polymer composites and the extracts of sea algae are used for cosmetics, pharmaceutical materials and food such as agar. Especially, algae fiber has so similar properties to cellulose in terms of crystallinity and functional groups that it can be utilized as reinforcements of biocomposites. Biocomposites as alternatives of glass fiber reinforced polymer composites are environmentally friendly polymer composites reinforced with natural fibers and are actively applying to the automobiles and construction industries. In this paper, characteristics of algae fiber and biocomposites reinforced with algae fiber as environmentally friendly energy materials have been introduced.

Various materials are used as electrical barrier materials, such as glass, insulating oil, gas, paper and polymer. These materials shut off electricity from conductor as a barrier and separate as well as support conductor from outside environment while using electrical equipment. Polymers are generally used for cable insulation material. Recently environmental regulation are reinforced and eco-friendly materials are in trend.
