INTRODUCTION
4. 재료의 분류
◎ Based on atomic bonds and structure
1) Metal : 자유전자에 의한 금속 결합
→ valence electron 들이 핵 (parent atom)에 묶여 있지 않고 자유롭게
이동하면서 전체를 결합시키고 있다.
- high electrical and thermal conductivity ← free valence electrons
- 불투명, 광택, 반사력 ← valence electron 이 빛을 받으면 전자기적으로
진동하면서 나타나는 현상
- 일반적으로(비교적), 무거움(밀도↑), 가공성이 높다
2) Polymer : 비금속 원소들 (주기율 오른쪽 윗부분)의 공유/배위 결합
→ 전자친화력이 높은 비금속 원소들이 공유 / 배위결합을 하면서 커다란 분자
(macromolecules)를 구성한다. 이 큰 분자체는 반복되는 단위분자 (mer)로
구성되어 있고, 이것이 반복되면서 Polymer를 이룬다.
-
가볍다 : low density
thermal & electrical insulator
반사력은 없고, 투과력이 있다 (적어도 thin film에서)
유연성, 변형이 쉽다
이것들은 모두
일반적 or 상대적
성질들이다 !
INTRODUCTION
3) Ceramic : 비금속 무기 화합물
→ 비금속 원소와 금속 원소의 화합물이다. 따라서 그 결합형태나
특징이 매우 다양하다.
ex) insulator ↔ superconductor
- 종류 : 산화물, 탄화물, 질화물 등
- 일반적 특성 : hard, brittle, high wear–resistance
high temperature performance …
