Abstract

본 발명은 상층면(19) 및 하층면을 갖는 지지층(3) 및 각각 다수의 가교결합된 분자를 포함하고 하나이상의 표면(19)과 화학적으로 결합된 다수의 하이드로겔-형성 중합체 입자(2)를 포함하는 흡수성 복합 구조체에 관한 것이다. 지지층 및 하이드로겔-형성 중합체 입자는 입자 분자를 가교결합할 수 있는 가교결합체로 연결한다. 이러한 방식으로 지지층의 신축성에 부정적으로 영향을 미치지 않고 복합 구조체의 바람직한 침투성을 유지하면서 입자는 건조 및 습윤 상태 모두에서 지지층에 확실하게 부착된다.

Description

지지층 및 가교결합가능한 하이드로겔 중합체 입자로 형성된 흡수성 복합 구조체(ABSORBENT COMPOSITE STRUCTURE FORMED OF A SUBSTRATE AND CROSS-LINKABLE HYDROGEL POLYMER PARTICLES)
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제3도는 본 발명의 흡수성 복합 구조체의 양태의 단면도이다.
