“…Two types of clays were studied in contact with ice: vermiculite, which gets charged in an aqueous medium, and two uncharged kaolin clays, pristine and washed. The contact angle for clays was not presented in [57]; at the same time, the literature data indicated the hydrophilic nature of the surface of the above materials with the contact angle around 30° [72]. High energy X-ray diffraction studies of QLL at kaolin/ice and vermiculite/ice interfaces [57] indicated some thickness increase with respect to those measured in the vicinity of SiO2 interfaces [59,60] for a low degree of supercooling.…”

Ice adhesion plays a crucial role in the performance of materials under outdoor conditions, where the mitigation of snow and ice accumulation or spontaneous shedding of solid water precipitations are highly desirable. In this brief review we compare the adhesion of water and ice to different surfaces and consider the mechanisms of ice adhesion to solids basing on the surface forces analysis. The role of a premelted or quasi-liquid layer (QLL) in the ice adhesion is discussed with the emphasis on superhydrophobic surfaces, and the temperature dependence of ice adhesion strength is considered with an account of QLL. We also very briefly mention some recent methods for the measurement of ice adhesion strength to the icephobic engineering materials outlining the problems which remain to be experimentally solved.

“…This phenomenon of increased hydrophobicity in hydrophilic particles following HA adsorption is well documented. For instance, Kholodov et al discovered that HA adsorption onto clay particles, including kaolin and montmorillonite, significantly elevated the WCA, in other words, amplifying hydrophobicity.…”

These changes were primarily attributed to the adhesion of HA to the surfaces of the MPs.…”

Microplastics (MPs) can be trapped in sea ice, acting as a temporary storage and transportation medium. The aim of this study is to investigate the interaction between aquatic organic matter and MPs and the roles of aquatic organic matter in the entrainment behaviors of MPs in ice formation processes. Our study investigated the effects of aquatic dissolved organic matter on the properties of MPs through a 28 day interaction experiment conducted under both UV and dark conditions. The implications of the alteration in MP properties on their entrapment in ice were also explored in an ice formation experiment. The presence of aquatic organic matter on the MPs after the interactions was confirmed, but the interaction with aquatic organic matter had different impacts on the two types of MPs. Furthermore, the entrapment of MPs in ice was improved after their interaction with aquatic organic matter due to surface damage caused by physical abrasion and UV radiation. These findings underscore the critical role that the inherent properties of MPs play in determining their environmental behavior. These properties can significantly impact their interactions with other natural components in the environment, thereby influencing their behavior in a cold environment.

Nanocellulose Hybrid Lignin Complex Reinforces Cellulose to Form a Strong, Water-Stable Lignin–Cellulose Composite Usable as a Plastic Replacement

The significant challenges in the use of cellulose as a replacement for plastic are its mechanical properties’ degradation and uncontrolled deformation during the rewetting process. Herein, inspired by the reinforcement of cellulose by lignin in natural plant tissue, a strong and water-stable lignin–cellulose composite (LCC) was developed. A nanocellulose hybrid lignin complex (CHLC) created from bagasse residue after enzymatic hydrolysis was added into a pulp of bleached fibre extracted from pine to produce a lignin–cellulose sheet. The lignin as a water-stable reinforcing matrix, via the hydrogen bonding of the nanocellulose in the CHLC with the fibre was efficiently introduced onto the fibres and the fibre network voids. Compared with a typical lignin-free cellulose sheet, the dry strength and wet strength of the LCC were 218% and 2233% higher, respectively. The developed LCC is an eco-friendly and biodegradable alternative to plastic.
