Abstract

Water-soluble polyvinylidene pyrrolidone/low density polyethylene (PVP/LDPE) blend polymer was fabricated for sinkhole restoration polymer pouch application. The mechanical property and water solubility were measured as a function of blended PVP and LDPE ratios. Increase of blended LDPE ratio caused the enhancement of tensile strength, elongation at break and storage modulus while water solubility decreased due to its non-soluble property. In order to enhance the mechanical properties, moreover, surface modified silica nanoparticle via silane coupling agent was adopted as a filler. As a result, the tensile strength was enhanced while water solubility was almost not influenced by additional silica filler.


지반 공극 복구용 수용성 고분자 파우치 소재 개발을 위하여 수용성 고분자인 polyvinylidene pyrrolidone (PVP)와 low density polyethylene(LDPE)를 블렌드하였다. 또한 두 고분자의 다양한 혼합비에 따른 기계적 물성 및 수용성 변화를 관찰하였다. LDPE의 함량이 증가함에 따라 인장강도와 신장률, 저장탄성률이 증가하였으며 수용해도가 감소하였다. 폴리머 블렌드의 기계적 물성을 강화하기 위하여 실리카 나노입자를 실란커플링제로 표면처리 후 필러로 복합화하여 고분자 블렌드의 인장강도 증가를 확인하였고, 용해도에는 실리카 필러가 커다란 영향을 미치지 않는 것을 확인하였다.
