“…Naturally occurring cellulose is found in two crystalline or allomorphic forms, Iα and Iβ, depending upon the network of hydrogen bonds formed between the hydroxyl groups of cellulose chains. Iα is predominantly found in plants, while Iβ is the form of cellulose produced by bacteria [ 177 ]. These allomorphs vary in their solubility because of the hydrogen bonding pattern.…”

The application of mulch films for preserving soil moisture and preventing weed growth has been a part of agricultural practice for decades. Different materials have been used as mulch films, but polyethylene plastic has been considered most effective due to its excellent mechanical strength, low cost and ability to act as a barrier for sunlight and water. However, its use carries a risk of plastic pollution and health hazards, hence new laws have been passed to replace it completely with other materials over the next few years. Research to find out about new biodegradable polymers for this purpose has gained impetus in the past few years, driven by regulations and the United Nations Organization’s Sustainable Development Goals. The primary requisite for these polymers is biodegradability under natural climatic conditions without the production of any toxic residual compounds. Therefore, biodegradable polymers developed from fossil fuels, microorganisms, animals and plants are viable options for using as mulching material. However, the solution is not as simple since each polymer has different mechanical properties and a compromise has to be made in terms of strength, cost and biodegradability of the polymer for its use as mulch film. This review discusses the history of mulching materials, the gradual evolution in the choice of materials, the process of biodegradation of mulch films, the regulations passed regarding material to be used, types of polymers that can be explored as potential mulch films and the future prospects in the area.

“…Cellulose, as the most abundant polysaccharide compound or polymer in nature, is widely considered as an ideal material to replace petroleum-based polymers due to its renewability, biodegradability, and sustainability (Zainul Armir et al 2021). In addition, its derivatives (nanofiber, nanocrystal, etc.)…”

Regeneration from cellulose solution is an effective way for processing and regulating the cellulose-based materials, during which the coagulation bath plays an important role that has been paid insufficient attention. Herein, we investigate the effect of polarity of the coagulation baths on the hydrophilicity of the regenerated cellulose, and the results show that polarity of the coagulation bath affects the crystalline assembly along different crystal plane by regulating the molecular interactions, leading to discriminating surfaces of hydrophilicity. Strong-polar coagulation bath, such as H2O, induces the regeneration of cellulosic molecules along 11¯0 crystal plane, leading to form hydrophilic nanosheets. Lowering the polarity of the coagulation baths results in fragmenting the morphology and reducing the hydrophilicity of the nanosheets that regenerate along the 110 or 020 crystal planes. Molecular dynamics simulations reveal the mechanisms for the interactions between the polar groups in cellulosic molecules and the hydrophilic facet of the regenerated cellulose. During the regeneration process, the cellulosic molecules are assembled under the influence of van der Waals interactions, resulting in crystallizing along the direction of 110 face to form the two-dimensional nanosheets. As the polarity of the coagulation bath changes from strong to weak, the assembly regeneration evolves from along 11¯0 to 110 or 020 crystal planes, which is recognized by the interaction changing from Van der Waals to hydrogen bond in cellulosic chains. As a result, the cellulose regenerates two-dimensional nanosheets with different hydrophilicity on the surface. The experimental and calculating results provide the feasibility for structural regulation of regenerated cellulosic materials with demand performance of different hydrophilicity.

Water is an indispensable strategic resource for biological and social development. The problem of oily wastewater pollution originating from oil spillages, industrial discharge and domestic oil pollution has become an extremely serious international challenge. At present, numerous superwetting materials have been applied to effectively separate oil and water. However, most of these materials are difficult to scale and their large–scale application is limited by cost and environmental protection. Herein, a simple, environmentally friendly strategy including sol–gel, freeze–drying and surface hydrophobic modification is presented to fabricate a bamboo cellulose foam with special wetting characteristics. The bamboo cellulose foam is superhydrophobic ,with a water contact angle of 160°, and it has the superoleophilic property of instantaneous oil absorption. Owing to the synergistic effect of the three–dimensional network structure of the superhydrophobic bamboo cellulose foam and its hydrophobic composition, it has an excellent oil–absorption performance of 11.5 g/g ~ 37.5 g/g for various types of oil, as well as good recyclability, with an oil (1,2–dichloroethane) absorption capacity of up to 31.5 g/g after 10 cycles. In addition, the prepared cellulose–based foam exhibits an outstanding performance in terms of acid and alkali corrosion resistance. Importantly, owing to bamboo cellulose being a biodegradable, low–cost, natural polymer material that can be easily modified, superhydrophobic/superoleophilic bamboo cellulose foam has great application potential in the field of oily wastewater treatment.
