Transparent bacterial cellulose nanocomposite hydrogels

Номер: US20130011385A1

Автор: Chandrakant J. Panchal, Wankei Wan, Xinsheng Li

Принадлежит: Axcelon Biopolymers Corp

A transparent polymeric nanocomposite hydrogel is provided, wherein the polymeric nanocomposite hydrogel is made from a water insoluble polymer, i.e. poly(2-hydroxyethyl methacrylate) (PHEMA) or/and crosslinked PHEMA and a water insoluble nanofiber, i.e., bacterial cellulose (BC). Disclosed is a synthetic route for polymeric nanocomposites hydrogels. The preferred polymeric nanocompositions are produced through free radical polymerization of HEMA monomer in the presence of bacterial cellulose with an assistance of ultrasound to enhance the mixing of bacterial cellulose, initiator, and the monomers. The polymeric nanocomposite hydrogel is then formed by immersion of the dry polymeric nanocomposite in water. Disclosed is a high transmittance polymer nanocomposite hydrogel with a preferred BC loading less than 0.1%, water content of about 40% in weight, good mechanical integrity and strength. The disclosed polymer nanocomposite hydrogel and compositions pertain to hydrogel applications, particularly contact lenses and optic components for biosensor.

A cooling sheet for photovoltaic modules, a method of manufacturing the same, a backsheet for photovoltaic modules, a method of manufacturing the same, and a photovoltaic module are provided. The cooling sheet for photovoltaic modules which includes a resin layer can be prepared by coating or impregnating one surface of a porous substrate with a super-absorbent polymer (SAP) containing a fluid. Here, the resin layer includes the fluid-containing SAP which is formed on one surface of the porous substrate or impregnated with the porous substrate. When the cooling sheet for photovoltaic modules is attached to the outside of the weather-resistant substrate to prepare the backsheet for photovoltaic modules, it is possible to suppress an increase in power generation temperature of a photoelectric cell by evaporation of the fluid, for example water, included in the SAP, thereby improving the power generation efficiency of the photovoltaic module.

Renewable Polyester Film having a Low Modulus and High Tensile Elongation

Номер: US20130209770A1

Принадлежит: Kimberly Clark Worldwide Inc

A film that is formed from a thermoplastic composition is provided. The thermoplastic composition contains a rigid renewable polyester and a polymeric toughening additive. The toughening additive can be dispersed as discrete physical domains within a continuous matrix of the renewable polyester. An increase in deformation force and elongational strain causes debonding to occur in the renewable polyester matrix at those areas located adjacent to the discrete domains. This can result in the formation of a plurality of voids adjacent to the discrete domains that can help to dissipate energy under load and increase tensile elongation. To even further increase the ability of the film to dissipate energy in this manner, the present inventors have discovered that an interphase modifier may be employed that reduces the degree of friction between the toughening additive and renewable polyester and thus reduces the stiffness (tensile modulus) of the film.
