Ⅲ. 봉합사(수술봉합사)의 종류
1. Absorbable Suture material의 종류와 특징
1) Catgut
○ Chromic Catgut
- 큰혈관의 결찰, 요로 및 담도계의 봉합
- 근육, 근막의 봉합은 장력의 급속한 감소로 사용안함
- By enzymatic 90day. Tension Strength : at least 28days(2주 40%, 4주 0%)
- Tan 황갈색 6/0 ˜ 3
Absorbency Material), AGM(Absorbent Gel Material)등 각기 다른 이름으로 부르고 있다.
③ 물질의 특징
⒜ 자기무게의 5백 ~ 1000배의 물을 흡수하는 합성 고분자이다.
⒝ 소수성과 친수성을 겸비, 백색 분말상의 고분자수지이다.
⒞ 물을 흡수하면 겔(Gel)상으로 변화한다.
⒟ 압력을 가해도 흡수된
such as visible or ultraviolet light
Absorption and generation of exciton
Dissociation and separation
Transport and collection
PCBM has a drawback and thus contributed very little to the absorption of solar light.
- using other acceptors which absorbs at longer wavelengths
- stacking solar cells based on materials that absorb in different wavelength region
3. Requirements of EUV resist
EUV is highly absorbed by all materials, even EUV optical components inside the lithography tool are susceptible to damage, mainly manifest as observable ablation. Such damage that is associated with the high-energy process of generating EUV radiation is a new concern specific to EUV lithography .
EUVL's shorter wavelength also increases flare, resulting in less
materials
Throughout the semester, specific materials are commonly used in particular apparel

Coolon
Developed by Kolon
Good moisture absorbency
Excellent excretion of moisture→ fast drying
Use of point touch method
→ not tight and comfortable
Aero Cool
Excellent absorbency and excretion of moisture
Special cross section controlling technique used
