Abstract:
본 발명은 상호연결된 연속기포형의 HIPE로부터 만들어진 불균질상 중합체상 발포체 구조물에 관한 것으로, 이때 발포체 구조물은 2개 이상의 별개의 영역을 갖는다. 이러한 불균질상 발포체는 다양한 용도로 사용되며, 예를 들면 에너지 및 유체 흡수, 절연 및 여과에 사용된다. 본 발명은 또한 수성 유체(특히 뇨 및 혈액과 같은 체액)와 접촉할 때 이들 유체를 포획하여 분배하고 저장할 수 있는 불균질상 흡수성 중합체상 발포체에 관한 것이다. 본 발명의 발포체는 상이한 밀도, 중합체 조성물, 표면 성질 및/또는 미소다공성 형태학적 성질을 갖는 2개 이상의 별개의 영역을 갖는다. 본 발명은 또한 높은 불연속상 유중수적형 유화액을 중합시킴으로써 불균질상 발포체를 수득하기 위한 방법에 관한 것이다. 한가지 양태에서, 본 발명의 방법은 2개 이상의 별개의 HIPE를 사용하며, 각각의 유화액은 비교적 소량의 오일상 및 비교적 다량의 수성상을 포함한다.
Abstract:
A porous body including, as a base resin, a crosslinked polymer obtained by crosslinking a polymer of an acrylic monomer and/or a styrene-based monomer. A storage modulus of the porous body is 5 kPa or more and 2000 kPa or less at 23° C., an apparent density of the porous body is 10 kg/m3 or more and 250 kg/m3 or less, and a molecular weight between crosslinking points of the crosslinked polymer is 1.0×104 or more.
Abstract:
Provided herein is a porous PLA-based monolith having a microstructure templated by an external phase of a HIPE, as well as processes of manufacturing the same and uses thereof.
Abstract:
The composition, advantageously an emulsion or a foam, includes an internal phase dispersed in a hydrophilic continuous phase, the percentage of the internal phase being higher than 50%. The emulsion composition contains nanocrystals of a polysaccharide other than cellulose, advantageously chitin, that are located at the interface between the internal phase and the hydrophilic continuous phase.
Abstract:
A method for producing a High Internal Phase Emulsion foam is provided that comprises forming a first High Internal Phase Emulsion from an oil phase comprising monomer, crosslinking agent, emulsifier; and an aqueous phase. The High Internal Phase Emulsion is pumped into a water bath. The High Internal Phase Emulsion cures in the bath.
Abstract:
Monomers and crosslinkers derived from renewable resources that can be used to produce flexible, microporous, open-celled polymeric foam materials having physical characteristics making them suitable for a variety of uses, are disclosed. Monomer compositions derived from renewable resources, and having short curing times for preparing foam materials from high internal phase emulsions are also disclosed.
Abstract:
A system for continuous High Internal Phase Emulsion (HIPE) foam production. A (HIPE) is produced then extruded onto a carrier sheet positioned on a belt surface.
Abstract:
A method of producing a monolithic metal or metal composite having a hierarchic pore structure, the method comprising the steps of: selecting a template material, said template material having a porous structure; contacting the template material with a solution of the or each metal to be structuralised; depositing the or each metal onto the template; washing the metal coated template before deposition of further metal; isolating the metal coated template material; removing, thermally, at least a portion of the template material.
Abstract:
The present invention relates to a High Internal Phase Emulsion (HIPE) and HIPE foams produced therefrom comprising two or more layers and having a photoinitiator.
