As a kind of semi-solid material, the gel has gained increasing attention due to the high demand for fundamental research and practical applications. Organogels are gels formulated with organic liquid phases, which are distinguished from hydrogels infiltrated with water/aqueous solutions in a three-dimensional network. Owing to their inherent semi-solid property, organogels manifest various unique characteristics, such as surface lubricity, and anti-drying capacity, arousing particular interests in diverse practical applications.

Global perspective

In a newly published review, the current advances of organogels are focused to provide recent progress of organogels in global perspective. First, fundamental understandings of organogels, ranging from the basic composition, gelation mechanism, fabrication strategy, and unique property, are fully summarised.

Then, an emphasis is placed on the most recent progress in emerging applications of organogels, including anti-icing, anti-fouling, droplet manipulation, drug delivery, food processing, etc. Finally, the remaining challenges and future prospects of organogel are addressed to enlighten novel fabrication approaches and applications in the future.

The review has been published in Progress in Organic Coatings, Volume 159, October 2021.
