The present invention relates to a composition for a hydrogel sheet including a cellulose ether, a gelling agent, and a gelling promoter, a hydrogel sheet prepared therefrom, and a method of preparing the hydrogel sheet. According to the present invention, the composition for a hydrogel sheet can be used to prepare a hydrogel sheet capable of maintaining the shape thereof without a support by limiting a type of the gelling agent and / or a viscosity of the cellulose ether included in the composition.

An organic siloxane composite material containing polyaniline / carbon black and a preparation method thereof are disclosed. The organic siloxane composite material containing polyaniline / carbon black consists of a plurality of polyaniline / carbon black composites distributed in organic siloxane precursor while the organic siloxane composite material containing polyaniline / carbon black includes from 10 to 30 weight percent of polyaniline / carbon black composites. The preparation method of organic siloxane composite material containing polyaniline / carbon black includes the steps of: distributing a plurality of polyaniline / carbon black composites in organic siloxane precursor to produce a first solution; and adding a cross-linking agent into the first solution, after reaction with each other, an organic siloxane composite material containing polyaniline / carbon black is produced.

A measuring probe for measuring in ground a parameter, the probe having an elongate body with a tip as a leading end and a head as a trailing end, the elongate body having a first and a second member which each extend in a longitudinal direction of the elongate body, the second member provides resistance against bending of the first member when the tip is advanced into the ground by hammering on the head.

Polyurethane foam compositions and processes to make flexible polyurethane foams are disclosed. Polyurethane foam is produced in the presence of additives comprising guanidine derivatives. Improvements in physical properties such as air flow, dimensional stability, tensile, tear, elongation and foam hardness is observed when these additives are present in polyurethane formulations. In addition, these additives can minimize polymer degradation under humid ageing conditions resulting in foam products with better mechanical properties.

A polyamide / hybrid carbon filler composite is disclosed. The composite includes a polyamide as a matrix and a hybrid carbon filler dispersed in and bonded to the polyamide matrix. The hybrid carbon filler is composed of a nano carbon and a carbon fiber. Also disclosed is a method for preparing the polyamide / hybrid carbon filler. The method includes simultaneously subjecting a mixture of a polyamide and a hybrid carbon filler to mechanofusion and plasma treatments.
