New Polymer Additive that De-adheres Upon Light Exposure

Researchers at UCR have developed a new additive that may be added to adhesives.  When the UCR compound additive and polymer adhesive are exposed to visible light, this significantly weakens the adhesive bond.  The additive and adhesive may be mixed at room temperature and then it may be applied to surfaces to adhere them together.  Upon exposure to light the surfaces de-adhere. Fig. a shows solid dye particles encapsulated between 2 glass slides which are glued together by the UCR additive incorporated into a polystyrene film. 532 nm irradiation causes the polystyrene adhesion to fail and the bottom slide to drop off in Fig. b, releasing the red dye into the surrounding water.  

Material For Thermal Regulation

Researchers at UCI have developed a lightweight, flexible thermal material that, due to the extent that it is stretched, allows for tunable control of heat flow.

Microporous membranes for the separation of enantiomers

Current methods used to separate racemic compounds on a large scale have limitations in cost, energy efficiency, and discontinuous processing. UCI researchers have synthesized a membrane made of chiral porous polymers that can separate enantiomers from racemic mixtures through continuous processing.

Pressure Sensitive Fabrics

Piezoelectric sensors have long existed to monitor applied pressures between two objects. In large applications with malleable substrates or where low cost is key, individual piezoelectric sensors are not practical. A variety of applications exist where monitoring the pressure being applied to a soft surface would providing meaningful insights into the system or subject under observation. For instance, in a long-term care setting where patients need to be monitored for pressure ulcers, a bedding material that could sense the pressure points between a person’s body and the mattress could alert care givers that an adjustment in body position is warranted. Likewise, in a sports training application, a pressure sensitive boxing ring canvas could track a boxer’s footwork, or punching power and hand speed if applied to the inside of a punching bag.   Pressure sensitive soft toys could also benefit from feedback that might differ when a child scratches behind their stuffed animal’s ears vs. rubbing its belly.  To achieve discrete sensing in these applications, a low cost bulk sensing system is needed.
