چکیده

Photocurable thermochromic and humidity responsive materials based on polyurethane acrylated (PUA) bis(1-butyl-3-methylimidazolium) tetrachloronickelate ([Bmim]2[NiCl4]) ionic liquid (IL) have been prepared with varying IL content up to 40 wt% within the polymer matrix. The influence of photopolymerization process, morphology, Young modulus electrical conductivity was evaluated. All present a total conversion at least 88%. presence influences morphology PUA, being observed porous network structure upon incorporation into PUA samples show Tg around room temperature, which is independent that decreases content. composites exhibit dependent thermochromism from colourless blue. Further, relative in colour change accessed for sample containing 20 [Bmim]2[NiCl4], variation thermally activated governed, 55% minimum value occur.

Use of Polyethylene Glycol Coatings for Optical Fibre Humidity Sensing

Humidity induced change in the refractive index and thickness of the polyethylene glycol (PEG) coatings are in situ investigated for a range from 10 to 95%, using an optical waveguide spectroscopic technique. It is experimentally demonstrated that, upon humidity change, the optical and swelling characteristics of the PEG coatings can be employed to build a plastic fibre optic humidity sensor. T...

Biochars as Innovative Humidity Sensing Materials

In this work, biochar-based humidity sensors were prepared by drop-coating technique. Polyvinylpyrrolidone (PVP) was added as an organic binder to improve the adhesion of the sensing material onto ceramic substrates having platinum electrodes. Two biochars obtained from different precursors were used. The sensors were tested toward relative humidity (RH) at room temperature and showed a respons...

Multifunctional hybrid materials for combined photo and chemotherapy of cancer.

Combined chemo and photothermal therapy in in vitro testing has been achieved by means of multifunctional nanoparticles formed by plasmonic gold nanoclusters with a protecting shell of porous silica that contains an antitumor drug. We propose a therapeutic nanoplatform that associates the optical activity of small gold nanoparticles aggregates with the cytotoxic activity of 20(S)-camptothecin s...
