오늘날 석유자원은 선박, 자동차, 각종 기계 연료유, 윤활유 등 여러 산업분야에 광범위하게 사용된다. Today, petroleum resources are widely used in various industrial fields, including ships, automobiles, various machine fuel oils, and lubricants.
그러나 이동이나 작업을 수행하는 동안 기름이 유출되어 주위환경을 오염시킬 수 있기 때문에 유출을 방지하거나 유출유의 확산을 최대한 억제하여야 한다. However, since oil may leak during movement or work and contaminate the surrounding environment, leakage should be prevented or the spread of spilled oil should be suppressed as much as possible.
강, 바다, 해양 등에 유출된 기름을 흡수하는 기술은 크게 오일 흡수제, 오일 펜스 및 오일 제거장치로 구분된다. Technologies for absorbing oil spilled in rivers, seas, oceans, etc. are largely divided into oil absorbents, oil fences, and oil removal devices.
오일 흡수제 기술은 고분자, 나노복합체 등을 사용하여 오일을 흡수하는 것으로서, 흡수제의 성분으로는 다공성 상호침투성 망상 공중합체, 팽창흑연, 폴리우레탄/산화아연 입자층/자성 입자층/지방산층 복합체, 부직포 적층체, 발수제 코팅 흡착포, 자성분말 함침 팽창흑연 등이 있다.Oil absorbent technology uses polymers, nanocomposites, etc. to absorb oil.

Oil fence technology is an adsorption oil fence that prevents oil from flowing over even when waves hit by varying the sizes of the upper buoyancy section and the lower skirt section, and an oil fence filled with EPDM rubber powder, bentonite, rice husk, and Styrofoam in a circular or square bag. , There are oil fences that combine a highly absorbent hydrophilic resin that easily absorbs moisture and a resin that easily absorbs oil.

도 2는 그래파이트 입자로 개질된 폴리우레탄 스폰지의 주사전자현미경(SEM) 이미지를 나타낸다. Figure 2 shows a scanning electron microscope (SEM) image of a polyurethane sponge modified with graphite particles.
함침 공정이 다수 회 수행됨에 따라 폴리우레탄 스폰지의 표면조도 및 코팅되는 그래파이트 입자의 양이 증가함을 확인할 수 있다. It can be seen that as the impregnation process is performed multiple times, the surface roughness of the polyurethane sponge and the amount of coated graphite particles increase.
도 3은 폴리디메틸실록산(PDMS)으로 개질된 폴리우레탄 스폰지의 주사전자현미경(SEM) 이미지를 나타낸다. Figure 3 shows a scanning electron microscope (SEM) image of a polyurethane sponge modified with polydimethylsiloxane (PDMS).
상기 PDMS는 폴리우레탄 및 그래파이트의 사이에 위치하여 폴리우레탄과 그래파이트의 결합력을 향상시키며, 스폰지의 소수성 특성을 강화시킬 수 있다. The PDMS is located between polyurethane and graphite, improves the bonding strength between polyurethane and graphite, and can strengthen the hydrophobic properties of the sponge.
