Special Issue Information

Dear Colleagues,

We are delighted to open this Special Issue, entitled “Carbohydrate Biopolymers”.

Typical carbohydrate biopolymers include animal carbohydrates (e.g., chitin, chitosan, chondroitin sulfate, hyaluronic acid), plant carbohydrates (e.g., starch, cellulose, seed gum, resin gum, plant extract gum) and microbial carbohydrates (e.g., xanthan gum, gellan gum, pullulan), as well as their related oligosaccharides derived from degradation biotechnology. Compared with synthetic plastics, carbohydrate biopolymers have the advantages of biocompatibility, biodegradability and sustainability. These carbohydrate biopolymers can be fabricated into functional materials such as films, coatings, gels, fibers, particles, or composites, and are widely used for different applications, including in the food industry, pharmaceutical industry and chemical industry.

The aim of this Special Issue is to discuss their extraction, purification, characterization, manufacturing, as well as their various applications in biomedical and green industry fields. We cordially invite you to contribute to the themed issue. Both original research and review articles are highly welcome.

Natural polymer-based adhesive hydrogels have garnered significant interest for their outstanding strength and versatile applications, in addition to being eco-friendly. However, the adhesive capabilities of purely natural products are suboptimal, which hampers their practical use. To address this, we engineered carboxymethyl cellulose (CMC) surfaces with complementary bases, adenine (A) and thymine (T), to facilitate the self-assembly of adhesive hydrogels (CMC-AT) with a nanofiber configuration. Impressively, the shear adhesive strength reached up to 6.49 MPa with a mere 2% adhesive concentration. Building upon this innovation, we conducted a comparative analysis of the shear adhesion properties between CMC and CMC-AT hydrogel adhesives when applied to delignified and non-delignified wood chips. We examined the interplay between the adhesives and the substrate, as well as the role of mechanical interlocking in overall adhesion performance. Our findings offer a fresh perspective on the development of new biodegradable polymer hydrogel adhesives. Full article

The use of hydrogels in wound dressings, which is pivotal for effective wound treatment, has been widely applied to diverse medical wound conditions. However, formulating natural hydrogels that combine robust strength and self-healing capabilities is a significant challenge. To overcome this, we successfully designed a natural nanocellulose self-healing hydrogel that can quickly self-heal and restore the complete hydrogel structure after injury to fill the injured area and protect the wound from external damage. Our study utilized modified natural polymer carboxymethyl chitosan (CMC), hydrazide-modified carboxymethyl cellulose nanofibers (HCNF), and cellulose nanocrystals modified by dialdehyde (DACNC) to fabricate the hydrogel. The amides containing more amino groups and HCNF in CMC can be used as cross-linking nodes, and the high aspect ratio and specific surface area of DACNC are favorable for the connection of many active hydrogels. The hydrogel is crosslinked by the dynamic imide bond and hydrazone bond between the amino group of CMC, the amide of HCNF, and the aldehyde of DACNC and has a double network structure. These connections can be readily reassembled when disrupted, enabling fast self-healing of hydrogels within five minutes. Moreover, HCNF and DACNC were incorporated as nano-reinforced fillers to bolster the hydrogel’s strength while preserving its high liquid absorption capacity (381% equilibrium swelling rate).
