“…The most common technique for the physical modification of cellulose is the adding of surfactants to aqueous cellulose dispersion, followed by freeze-drying [ 116 , 117 , 118 ]. The success of modification of cellulose via adsorption was testified by several groups by such methods for structure characterization as Fourier transform infrared (FTIR) spectroscopy [ 115 , 118 , 119 , 120 ] and solid-state 13 C NMR spectroscopy [ 116 ]. Besides these, a decrease in turbidity also can indirectly testify the surface modification.…”

Aliphatic polyesters/cellulose composites have attracted a lot attention due to the perspectives of their application in biomedicine and the production of disposable materials, food packaging, etc. Both aliphatic polyesters and cellulose are biocompatible and biodegradable polymers, which makes them highly promising for the production of “green” composite materials. However, the main challenge in obtaining composites with favorable properties is the poor compatibility of these polymers. Unlike cellulose, which is very hydrophilic, aliphatic polyesters exhibit strong hydrophobic properties. In recent times, the modification of cellulose micro- and nanomaterials is widely considered as a tool to enhance interfacial biocompatibility with aliphatic polyesters and, consequently, improve the properties of composites. This review summarizes the main types and properties of cellulose micro- and nanomaterials as well as aliphatic polyesters used to produce composites with cellulose. In addition, the methods for noncovalent and covalent modification of cellulose materials with small molecules, polymers and nanoparticles have been comprehensively overviewed and discussed. Composite fabrication techniques, as well as the effect of cellulose modification on the mechanical and thermal properties, rate of degradation, and biological compatibility have been also analyzed.

Digital printing waste paper fiber/nano-crystalline cellulose/poly (lactic acid) (DPF/NCC/PLA) composites, modified through γ-methacryloxy propyl trimethoxy silane (KH570), isopropyl tri (dioctylpyrophosphate) titanate (TMC201), sodium hydroxide (NaOH), polyethylene glycol 6000 (PEG6000), and a composite silane coupling agent (KH570/PEG6000), were fabricated by melt blending and injection molding and the effects of different modifiers on the properties of composites were studied. Results showed that mechanical properties of the modified composites generally improved, and the best mechanical properties, including flexural, tensile and impact strength, were achieved PEG6000, KH570/PEG6000, and KH570 modification, respectively. Thermal performance analysis showed improved thermal properties of composites treated by KH570, but the crystallinity of the modified materials was increased. Both water absorption and degradation properties showed a decreasing trend, and water absorption performance was obviously improved after KH570/PEG6000 modification. Under the action of several modifiers, the diffusion coefficient, thermodynamic solubility and permeability of composites were reduced to varying degrees. Furthermore, scanning electron microscopy (SEM) demonstrated that interfacial adhesion and composite compatibility were improved with significantly fewer and smaller pores, as well as a fuzzy boundary among the three phases.

“…Researchers have attempted various physical, chemical, and biological treatments to reduce the hydrophilic nature of the fiber as well as to improve the polymer-fiber interaction. [8][9][10] However, this approach requires additional experimental steps, which can increase the time and cost of processing. An alternative and easier approach to improve the molecular interaction is to incorporate a coupling agent in the composite formulation.…”

Natural fiber-reinforced composites (NFRC) are cheaper and more eco-friendly alternatives compared to synthetic composites for automotive applications. As there is limited understanding about the balance of different physical properties in NFRC, optimizing these properties is an important consideration for a more widespread application of NFRC. The goal of this research was to statistically develop an optimum formulation for oat-hull-reinforced polypropylene composite. Mechanical properties of the composites were first experimentally measured. Then, the mixture design experiment approach was utilized to generate response models for different properties and diagnostic tools were utilized to validate the models. In addition to optimizing the desired material properties, the overall cost of the composite was minimized, which adds novelty to the work.
