Only a few studies have investigated the ice nucleating ability of microplastics. Ganguly and Ariya synthesized three microplastics types (polypropylene, low-density polyethylene, and highdensity polyethylene) in the laboratory and quantified their freezing properties using a droplet freezing technique. Teska et al. investigated the ice nucleation ability of fibers from casual apparel consisting of acrylic, polyester, nylon, and a combination of cotton, polyester, viscose and elastane.
