摘要:
The present invention relates to a hydrochromic polydiacetylene composite composition, a hydrochromic thin film using same, and a use thereof, and more specifically, to a hydrochromic polydiacetylene composite composition reacting sensitively to moisture, providing the hydrochromic thin film using same, and to applying same to biorecognition or fingerprint recognition. According to the present invention, moisture secreted from a fingerprint or pores on the skin can be detected with high sensitivity. Thus, the position of pores unique to a fingerprint of an organism can be amplified and displayed through selective color change and fluorescent change patterns exhibited when moisture is absorbed.
摘要:
A method is described for inserting or dispersing quartz within a substrate containing polymers polarizable by an electromagnetic field having electrical resistivity, from an insulator to conductor or vice versa, modifiable by said field. The method involves dispersing in the substrate particles having a sandwich structure including two conductive layers and a layer with piezoelectric characteristics in the middle.

Provided is a film-forming method based on an LB method by which a uniform alignment film using a helical polyacetylene can be obtained. The method based on the LB method includes: developing a helical polyacetylene onto a liquid surface; and transferring a monolayer film of the helical polyacetylene formed on the liquid surface onto a substrate to form a film, in which a compressibility P represented by the following formula (1) at a time of the film formation is 1×10−2 m/mN or less: P=(1/(dH/dS))×(1/S) (1), where H represents a surface pressure (mN/m) of the monolayer film of the helical polyacetylene, and S represents an area (m2) of the monolayer film of the helical polyacetylene developed onto the liquid surface.

摘要:
Electrically conductive polymer blends of an acetylene polymer, such as poly(acetylene), and a triblock thermoplastic elastomer, such as styrene-butadiene-styrene, are disclosed. In addition, a method for preparing such blends wherein the acetylene polymer is preferentially formed in the central elastomeric block of the triblock copolymer is disclosed. These blends exhibit high conductivity and elasticity upon doping with electron donors or electron acceptors.

This invention relates to a process for producing an organic semiconductor. More specifically, it relates to a process for producing an electrically conductive acetylene high polymer, which comprises doping an acetylene high polymer having a fibrous microcrystalline (fibril) structure with a specified electron acceptor compound having low toxicity, to obtain an electrically conductive acetylene high polymer having an increased electrical conductivity, and flexibility and heat stability.
