A straightforward photo-annealing approach was developed for building functional polymer layers on paper. Conducting polyaniline with the ability for photothermal conversion can be readily annealed by near-infrared light. The annealed polymers become both insulating and hydrophobic. Selective photo-annealing produces a functional layer with patterned conductive arrays. This material exhibits re...

We study the thermal insulation of a bounded body $\Omega\subset\mathbb{R}^n$, under prescribed heat source $f>0$, via bulk layer insulating material. consider model transfer between insulated and environment determined by convection; this corresponds to Robin boundary conditions on free layer. show that minimal configuration exists it satisfies uniform density estimates.

We analyze the extracellular stimulation current and charge injection capacity (CIC) of microelectrodes coated with an insulating layer to prevent toxic electrochemical effects in bioelectronic applications. show for a microelectrode ferroelectric that polarization contributes current. Depending on remanent Pr ferroelectric, switching regime can increase CIC by up two orders magnitude as compar...

We have prepared different hybrid polymer-phthalocyanine materials by solution processing, starting from two sulfonated phthalocyanines, s-CoPc and CuTsPc, and polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), poly(acrylic acid-co-acrylamide) (PAA-AM), poly(diallyldimethylammonium chloride) (PDDA) and polyaniline (PANI) as polymers. We also studied the response to ammonia (NH3) of resistor...
