Abstract:
Provided is a system for producing electricity, the system having an object configured to move in at least one of, an upward direction, a downward direction, a left direction, a right direction, an eccentric motion, a straight line, or a circular motion; and at least one piezoelectric element attached to the object, wherein, when the object is moving, the object is configured to apply a pressing force to the at least one piezoelectric element to produce the electricity.
Abstract:
A method for patterning a conductive polymer that adheres well to an oxide layer is presented. The method includes forming a self-assembled monolayer on a substrate, patterning the self-assembled monolayer, forming a catalyst layer on the self-assembled monolayer, and forming a conductive polymer layer on the self-assembled monolayer.
Abstract:
This invention relates to a resin composition using a dicarboxylic acid diester derivative as a plasticizer, and particularly to a resin composition, which is obtained by adding the plasticizer to one or more resins selected from among aliphatic or aromatic polycarbonate resins, polyurethane resins, polyvinyl chloride resins and epoxy resins, and which has a low glass transition temperature (Tg) and can be easily processed and can impart flexibility to products. This plasticizer exhibits high plasticization efficiency, and a resin composition including the plasticizer can manifest a low glass transition temperature and good flexibility at low temperature, thus improving physical properties such as tensile strength, even when only a small amount of the plasticizer is added.
Abstract:
The present invention provides an ester plasticizer for polyvinyl chloride (PVC) resin, epoxy resin or urethane resin and a method of preparing the same. More particularly, the present invention provides an ester plasticizer using triacetin and coconut oil-based biodiesel as raw materials, which can prepare a resin composition having excellent plasticizing efficiency and improved physical properties such as tensile strength and the like.When a polyvinyl chloride resin or the like is manufactured using the ester plasticizer, there are advantages in that an environment-friendly product having an excellent plasticizing efficiency and in that the physical properties such as hardness, tensile strength, etc. of the product are improved.
