Construction of large-sized ultra-black films for efficient solar-thermal conversion under harsh environmental conditions

A special surface structure is required to achieve ultra-black absorption for efficient solar-thermal conversion. However, such a structure developed so far suffers from deficiencies such as small size, low tolerance to external mechanical and chemical attacks, and lack of reparability. In this stud...

Description
Summary:A special surface structure is required to achieve ultra-black absorption for efficient solar-thermal conversion. However, such a structure developed so far suffers from deficiencies such as small size, low tolerance to external mechanical and chemical attacks, and lack of reparability. In this study, we propose two facile methods to prepare ultra-black films with polyaniline (PANI) and polydimethylsiloxane (PDMS) by template replicating or acid etching. Experimental results show that the diffuse reflectance can be controlled to be
