Special Issue Information

Dear Colleagues,

We are pleased to announce our upcoming Special Issue, entitled "Design, Preparation, Characterization, and Applications of Functional Nanomaterials." This Special Issue is dedicated to exploring the diverse landscape of functional nanomaterials with certain spatial structures (0D, 1D, 2D, and 3D), including carbon nanotubes, graphene, carbon fibers, nanocellulose, MXene, organic and inorganic nanomaterials, and more, delving into their design, synthesis, characterization, and multifaceted applications.

Our Issue will provide a dynamic platform for researchers in the realm of functional nanomaterials, allowing them to exchange ideas, share their latest findings, and foster collaboration. We welcome contributions in the form of original research papers, communications, and comprehensive reviews. The scope of accepted topics is broad, encompassing, but not limited to, the following:

Efficient methods for the design and preparation of functional nanomaterials and composite materials: includes carbon nanotubes, graphene, carbon fibers, nanocellulose, MXene, as well as organic and inorganic nanomaterials and their derivatives;
Characterization of nanomaterial structures and properties: exploring the intricate structures and chemical properties of nanomaterials;
Applications of functional nanomaterials in cutting-edge technologies: lithium-ion batteries, fuel cells, supercapacitors, solar cells, electrocatalysis, flexible sensing and related areas;
Application of functional nanomaterials in traditional applications: anti-corrosion coating, food and daily chemicals, papermaking and biomass functional materials, environment engineering, textile printing and dyeing, chemical catalysis, and rubber and plastic field.

We invite you to share your pioneering research and discoveries in this rapidly evolving and highly promising field. Together, we can advance the understanding and utilization of functional nanomaterials.

Abstract

Two types of cellulose nanofibrils (CNFs) were isolated from cotton linter fibers and hardwood fibers through mechanical fibrillation methods. The dialdehyde cellulose nanofibrils (DACNFs) were prepared through the periodate oxidation method, and their morphological and structural properties were investigated. The characteristics of the DACNFs during the concentration process were also explored. The AFM analysis results showed that the mean diameters of wood fiber-based CNFs and cotton fiber-based CNFs were about 52.03 nm and 69.51 nm, respectively. However, the periodate oxidation treatment process obviously reduced the nanofibril size and destroyed the crystalline region of the nanofibrils. Due to the high crystallinity of cotton fibers, the cotton fiber-based DACNFs exhibited a lower aldehyde content and suspension stability compared to the wood fiber-based DACNFs. For the concentration process of the DACNF suspension, the bound water content of the concentrated cotton fiber-based DACNFs was lowered to 0.41 g/g, which indicated that the cotton fiber-based DACNFs could have good redispersibility. Both the wood fiber-based and cotton fiber-based DACNF films showed relatively good transmittance and mechanical strength. In addition, to the cotton fiber-based DACNF films had a very low swelling ratio, and the barrier water vapor and oxygen properties of the redispersed cotton fiber-based DACNF films decreased by very little. In sum, this study has demonstrated that cotton fibers could serve as an effective alternative to wood fibers for preparing CNFs, and that cotton fiber-based DACNFs have huge application prospects in the field of packaging film materials due to their stable properties during the concentration process.
