- NIST debuts new sensor development
AN IMPROVED METHOD MAY BE useful as a general technique for reproducibly fabricating microdevices such as sensors for detecting toxic chemicals. Two NIST microheater devices, each about 100 micrometers wide. On the left is a microheater coated with a conducting polymer, polyaniline, which is naturally green in color. On the ......
- UV Curing.
A UV curing process can finishers a number of advantages, including floorspace required, increased productivity and a high-quality finish ... Ultraviolet curing--the process of transforming a liquid into a solid by the use of light--is an energy efficient and relatively low-temperature technology with many applications in coating, printing, adhesives, electronics ......
- Mold-release agents.
ADELL PLASTICS, INC. Proprietary silicone fluid concentrates for all thermoplastics improve mold release, reduce overall cycle time, reduce rejects, and improve part wear and bearing properties. Also multifunctional concentrates. AIR PRODUCTS AND CHEMICALS INC. Pura water-based external release agents are said to allow excellent release and reduced build-up on molds, ......
- Smart Materials Based on Functionalized Conjugated
Polymers.
This article reviews how some conjugated polymers can detect and transduce chemical or physical information into an optical or electrical signal. There is hardly an aspect of our lives that is not touched by synthetic polymers. In the field of optics and electronics, these materials were traditionally used in applications ......
- How to injection mold cyclic olefin
copolymers.
This new family of clear engineering thermoplastics made its first big splash in extrusion, but now injection molders are learning how to process these amorphous resins into optical and medical parts. The first substantial wave of molded applications for the Topas family of metallocene-catalyzed cyclic olefin copolymers (COOs) is just ......
- Solid-state technique for making conductive polymers
Researchers at the Univ. of California at Los Angeles have developed the first solid-state process for synthesizing poly(3,4-ethylenedioxythiophene), or PEDOT, reports Fred Wudl, professor of chemistry and materials. PEDOT is one of the most successful conducting polymers used in industry. Current processes for making conducting polymers suffer from the fact ......
- New UV polymerisation: Dr Jeffrey K Okamitsu et al
explain how a process for free radical UV polymerisation results in
reduced premature termination and enhanced properties of UV cured
films.
UV polymerisation of coatings, adhesives, and inks is a very powerful, value-added process that is used in a wide range of applications including graphic arts, optical disc fabrication, flat-screen display manufacture, ink jet printing, converting, and automobile manufacture, to name a few. Many of these applications place significant functional and ......
