New polymer films conduct heat instead of trapping it

Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitt, or a Styrofoam coffee cup, both manufactured from polymer materials that are excellent at trapping heat.

Controlling thermal conductivity of polymers with light

Polymers are regularly used as thermal insulators for everything from keeping beverages hot to keeping sensitive electronics cool. In some cases, polymers can even be used as thermal conductors to enable efficient heating ...

Polymer power potential

The mantra 'reduce, reuse, recycle' is increasingly pertinent. Every year, vast amounts of energy that could be captured and reused are lost through waste heat. Now, A*STAR scientists have demonstrated, through theoretical ...

A sustainable and recyclable thermoelectric paper

Thermoelectric materials, capable of transforming heat into electricity, are very promising for converting residual heat into electrical energy, as they convert hardly usable or nearly lost thermal energy in an efficient ...

Doubling the efficiency of organic electronics

Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just ...

Hydrogel-based electrodes for brain implants developed

Hydrogels are physical and chemical polymer networks capable of retaining large quantities of liquid in aqueous conditions without losing their dimensional stability. They are used in a whole host of applications, and in ...

Engineers turn plastic insulator into heat conductor

Plastics are excellent insulators, meaning they can efficiently trap heat - a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic ...

'Random walk' of heat carriers in amorphous polymers

The intrinsic structure of amorphous polymers is highly disordered with long, entangled molecular chains. They are usually considered as thermal insulators due to their ultra-low thermal conductivity. One effective way to ...
