“…To this end, Liu et al [10] have prepared UV-curable hybrid coatings that have zero VOC content, which corroborates whatKhatoon et al [23] affirmed that researchers are moving toward utilising green and sustainable resources to substitute petroleum-based polyols (ethylene and propylene oxides) and diisocyanates [10,23]. Therefore, developing organic coatings from renewable sources presents viable alternatives to using chemicals from petroleum sources that are not eco-friendly [26,27,25].…”

“…The search also includes ecological balance and sustainable development [17,23,7], using recycled materials, and lowering volatile organic compound(VOC) emissions [24]. VOC refers to gases emitted from products or processes which enable rigid acrylic polymers to form films at ambient temperature [25]. These gases could either be harmful or react with other gases to further pollute the air and harm the people or the ecosystem.…”

Coatings are surface protection applications providing decorative, functional, or both applications on their applied substrates. Its application on substrates can be ingases, liquids, or solids. The environmental issues stemming from coating application, especially those from petroleum base feedstock, cannot be over-emphasised.This paper is poised to examine the merits of biodegradable synthesised polymeric coatings from a renewable source (plant seed oils).Using seed oil as a feedstock for organic coatings involves functionalising the seed oil to create a reactive site for polymerisation.The use of nanoparticles also helps to fine-tune coatings properties, and sometimes they provide thermal stability, adhesion, chemical resistance, electrical conductivity, anticorrosive, antimicrobial, hydrophobicityproperties, etc.

“…Yu et al observed that the unmodified CNC composite film has more white spots of different sizes and poor dispersibility, while the modified composite film has a uniform distribution of white spots and good dispersibility . Dogan-Guner et al measured the diameter and average spacing of white spots in SEM images, which suggested that the well-dispersed CNC improved interaction between the matrix, thus enhancing interfacial adhesion . The interfacial adhesion force is usually used to judge the interfacial morphology in SEM images, whether it is embedded in the matrix or pulled out.…”

Cellulose nanocrystals (CNCs) are hydrophilic nanoparticles extracted from biomass with properties and functions different from cellulose and are being developed for property-oriented applications such as high stiffness, abundant active groups, and biocompatibility. It has broad application prospects in the field of composite materials, while the dispersibility of the CNC in polymers is the key to its application performance. Many reviews have discussed in-depth the modification strategies to improve the dispersibility of the CNC and summarized all characterization for the CNC, but there are no reviews on the in-depth exploration of dispersion characterization. This review is a comprehensive summary of the characterization of CNC dispersion in the matrix in terms of direct observation, indirect evaluation, and quantified evaluation, summarizing how and why different characterization tools reveal dispersibility. In addition, "decision tree" flowcharts are presented to provide the reader with a reference for selecting the appropriate characterization method for a specific composite.

The results of a study on latexes obtained by emulsion copolymerization of acrylic, methacrylic and vinyl monomers without surfactants are presented. The monomers included ethyl acrylate and butyl acrylate, methyl and butyl methacrylate and methacrylic acid. The yield of the copolymerization reaction, the polymer concentration in the latex, the pH, surface tension, intrinsic viscosity number, Huggins constant, the molecular weight of the polymer and the particle size in the latex were determined. The stability of the latexes was tested by determining the values of non-overt and overt coagulation thresholds. The values of the limiting equivalent conductivity and the anode zeta potential were determined. The relative hardness of latex membranes and their mass change after hot water extraction were investigated. The relationships between the properties of individual latexes were established. The main aim of the research was to determine the influence of copolymer composition on the electrokinetic properties of polymer particles in latex. They determine the possibility of developing a new type of paint for electrophoretic painting with the use of latexes.
