A Degradable and Recyclable Photothermal Conversion Polymer

Chemistry – A European Journal, 2018
AbstractDecomposition and repolymerization of conjugated polymers offer great promise for developing recyclable photothermal conversion materials, which yet remain challenging. Herein, a crosslinked conjugated polymer based on a dynamic covalent bond of Schiff base is developed. This polymer possesses photothermal conversion efficiency as high as 90.4 %

Selective Coatings for Photothermal Conversion

1986
One of the simplest and most direct methods of harnessing solar energy is to convert the incident solar radiation into heat (called photothermal conversion). A variety of flat plate and concentrating type of collectors for this purpose have been designed and studied, and are being manufactured worldwide.

Cu7.2S4 nanocrystals: a novel photothermal agent with a 56.7% photothermal conversion efficiency for photothermal therapy of cancer cells

Nanoscale, 2014
Copper sulphides, as a novel kind of photothermal agent for photothermal therapy (PTT) of cancer cells, have attracted increasing attention in recent years due to good photostability, synthetic simplicity, low toxicity and low cost. However, the unsatisfactory photothermal conversion efficiency of copper sulphides limits their bioapplication as PTT ...

Melanin–Perovskite Composites for Photothermal Conversion

Advanced Energy Materials, 2019
AbstractBiomacromolecular pigments, such as melanin, play an essential role in the survival of all living beings. Melanin absorbs sunlight and transforms it into heat, which is crucial for avoiding damage to skin cells. Light absorption produces excited electrons, which could either fall back to ground states by releasing the heat (photothermal effect)

Materials for photothermal solar energy conversion

Journal of Materials Science, 1983
Commencally or potentially available selective and non-selective absorber surfaces for solar heat collectors are reviewed and the state-of-the-art of solar collector corrosion processes is outlined. The review of available published literature has indicated that a lack of quantitative information exists, relative to corrosion of collector surfaces ...

Texture of selective surfaces for photothermal conversion

Solar Energy Materials, 1991
Abstract The surfaces of selective solar absorbers prepared with an original conversion treatment of ferritic steel are characterized with different methods and more particulary with electrochemical ones (voltammetric and impedance diagram determinations). The coating is a microporous and rough medium presenting a fractal structure.
