Abstract
A light-reflecting member includes a resin composition having a porous structure. The porous structure may be formed by infiltrating/exhausting a super critical fluid into/from a resin composition. A resin composition is mixed and heated at a temperature no less than about a glass transition temperature. A super critical fluid is infiltrated into the resin composition at a pressure no less than about a critical pressure. The super critical fluid is released from the resin composition by decompressing the resin composition to an atmospheric pressure to form a porous structure.
Claims18
A light-reflecting member, comprising:
- a resin composition having a porous structure, the porous structure being formed by an infiltration of a super critical fluid into a resin composition, and a subsequent release of the infiltrated super critical fluid from the resin composition.
A method of forming a porous structure, comprising:
- infiltrating a super critical fluid into a resin composition;
- and
- releasing the super critical fluid from the resin composition.
A method of manufacturing a light-reflecting member, comprising:
- heating and mixing a resin composition at a temperature that is equal to or greater than about a glass transition temperature;
- infiltrating a super critical fluid into the resin composition under a pressure that is equal to or greater than about a critical pressure;
- and
- releasing the super critical fluid from the resin composition by decompressing the resin composition to an atmospheric pressure to form a porous structure.
