Photo-responsive polymers applications

Photo-responsive polymers properties, synthesis and applications... 

To date, heat-triggered shape memory polymers have had the greatest share of research and application adaptation. However, trigger mechanisms could also be chemo-responsive, e.g., water, ethanol, and pH change photo-responsive, e.g., UV or IR, including radio waves and/or mechano-responsive, e.g., stretching, impact, etc.

Two routes toward positive-type proofs were discovered. R. D. Kempf of Towanda R D showed that the dual response system, in which a visible exposure gave rise to an inhibitor, followed by a flooding UV exposure yielded masters, which could be toned with our conventional liquid toning system, and gave positive-working proofs. This was an illustration of applying the photo-polymer technology of HABI chemistry for yet another application. 

Acetylcholineesterase and choline oxidase Enzymes were entrapped in a photo-cross-linkable polymer. Detection of H202 liberated from the enzyme reaction. The range of application was 20-750 pM for ACh. Response time was 2-4 min. The immobilized enzyme membranes were very stable, and stored in a dry state. [69]... 

Light has been an important resource in polymer chemistry since the introduction of photo-initiated polymerisations. As this is, however, not the topic of this section, we will focus on advanced applications of light in polymer science including two-photon polymerisation and light-responsive materials.
