It is a manufacturing technology for pH indicator materials that do not have pigment leaching. Various application developments are expected.
Conventional pH measurement methods (litmus paper, glass electrode meters) have the issue of internal reagents leaching into the measurement solution. This technology has achieved a pH indicator copolymer that does not leach into the measurement solution by polymerizing pH dyes. 【Features of the Technology】 - Repeated measurements and long-term monitoring are possible. - There is no dye leaching into the measurement target. - Design for pH ranges (entire range, acidic, neutral, basic) is possible. - It can be made into films and fibers. 【Applications of the Technology】 - Development of pH sensors We are advancing the development of pH sensors through colorimetric measurement of the film-formulated pH indicator copolymer. - Fiberization By introducing it into chemical fibers, it is possible to realize fibers and non-woven fabrics with pH indicator functions. By film-forming and fiberizing the pH indicator copolymer, various application developments are expected.
