Slide # 3 Coming from a Long Way, Polymer Becomes Very Personal * 의료용 고분자 : 생체 분해성 고분자는 단순 가수분해 또는 효소의 작용으로 분해소멸되는 고분자이다. 대부분의 합성고분자는 분해되 지 않지만, 일부 지방족 폴리에스터 혹은 폴리카보네이트들은 가수분 해에 의해 천천히 분해된다. 치과용 고분자로는 구강내 특수한 상황으 로 요구특성이 매우 까다로와, PMMA 와 bis-GMA 계 복합재가 주종을 이룬다. 혈액투석기, 혈장분리기, 인공심폐기등에 쓰이는 분리막 소재 로는 PMMA, PP, PAN, polysulfone, cellulose, PVA, PE, poly(ethylene-co- vinylacetate) 등이 사용된다. * 콘택트 렌즈 : 초기에 개봘된 PMMA 는 투명하 고 기계적 강도는 우수하나 착용감이 나쁘고 산 소투과성이 거의 없으므로 시장에서 쇠퇴하고, 최근에 많이 쓰이는 경질 콘택트 렌즈에 재료로 서 PHEMA(poly hydroxyethylmethacrylate) 계 친 수성 하이드로젤을 사용한다. PMMA 에 비하여 기계적 강도는 떨어지지만, 친수성이며 산소투 과성이 높아 널리 사용된다. 인공 뼈 인공피부 인공혈관 After Lee, 2004 Source: UML Nylon in 1940 Plastic Now

Slide # 4 Hip Implant With age or certain illnesses joints deteriorate. Particularly those with large loads (such as hip). Adapted from Fig , Callister 7e. Hip Implant Requirements –mechanical strength (many cycles) –good lubricity –biocompatibility

Slide # 5 Hip Implanting Using plastics Key problems to overcome –fixation agent to hold acetabular cup –cup lubrication material –femoral stem – fixing agent (“glue”) –must avoid any debris in cup
