Quality Control of 1,4-Bis(bromomethyl)benzene The article mentions the following:
A smart surface with converse temperature-dependent (CTD) wettability was fabricated from an upper critical solution temperature-type (UCST-type) poly(acrylamide-co-acrylonitrile) (P(AAm-co-AN)) copolymer. The obtained surface exhibits a remarkable and reversible hydrophobic-hydrophilic transition depending on temperature with a high response rate. The static water contact angle of the surface decreases from 103° ± 2° to 60° ± 1° as the temperature increases from 30°C to 80°C. Further, the wettability of the UCST-type surface shows a pos. linear relationship between wettability and temperature This study for the first time provides an UCST-type smart surface with wettability that decreases by over 35° as the temperature increases by only 20°C. In the experiment, the researchers used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Quality Control of 1,4-Bis(bromomethyl)benzene)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.Quality Control of 1,4-Bis(bromomethyl)benzene Organobromine compounds have fallen under increased scrutiny for their environmental impact.
