Efforts to prevent ice accretion on surfaces have had limited success to date. A more realistic goal is the production of durable, industrially viable coatings that reduce ice adhesion rather than completely prevent its formation. New, more effective, durable, reliable and cost-efficient methods of reducing ice formation on different surfaces are being developed that will enhance product value, increase safety in critical applications such as aerospace and also be of benefit to a large number of other technical areas and applications. These novel technologies include (1) hydrophobic, functionalised layers with a nano-structure with outstanding anti-ice effects, (2) the use of chemical freezing point depressors to produce temporary anti-ice coatings, (3) the synthesis of anti-freeze proteins and their coupling to paint matrices to produce biomimetic anti-ice coatings, (4) passive coatings that reduce ice formation through nano-hydrophilic centres in a hydrophobic environment.
