Effects of Three Different Types of Aloin on Optical, Mechanical, and Antibacterial Properties of Waterborne Coating on Tilia europaea Surface

Abstract

The microcapsules were prepared by using melamine-formaldehyde resin as the wall material and aloin as the core material. The aloin was dissolved in ethanol and water to prepare microcapsules. The aloin powder, the aloin microcapsules prepared with ethanol as the solvent, and the aloin microcapsules prepared with water as the solvent were, respectively, added to the waterborne coating with different contents and coated on the surface of Tilia europaea. The effects of different modifiers and contents on the coating’s optical properties, mechanical properties, and antibacterial properties were explored. The results showed that the aloin microcapsules prepared with ethanol as the solvent had good morphology and comprehensive properties. When the content was 7.0%, the color difference of the waterborne coating was small, the adhesion was grade 3, the impact resistance was 12 kg·cm, and the antibacterial rate was 87.8%. In terms of antibacterial properties, the uncoated aloin powder, the coated aloin microcapsules prepared with ethanol as the solvent, and the aloin microcapsules prepared with water all have certain antibacterial properties and the antibacterial rates reached 99.2%, 97.3%, and 67.3%, respectively. This study provides a certain reference for developing antibacterial wood furniture coatings.

Microcrystalline Cellulose from Aloe Plant Waste as a Platform for Green Materials: Preparation, Chemical Functionalization, and Application in 3D Printing

“…A part of these components can be of interest for different applications considering their antimicrobial or optical properties and will be utilized in further studies. 21,22 Following the characterization of the original material, the cellulose extraction process was developed and the final powder obtained was first characterized by XRD, comparing its pattern to that of commercial MCC and to that of untreated waste, i.e., Aloe Peel powder (Figure 1a). As expected, the data show that Aloe Vera presents a similar pattern to commercial MCC, with crystallinity is of type I, and a high width at half height, suggesting that the isolated material possesses nanocrystalline domains.…”

“…During the first step of the biomass treatment, Aloe powders were subjected to extraction using ethanol to remove lipidic fraction, chlorophylls, and the majority of anthraquinone species (AQs), which were then determined by HPLC analysis (Table ). A part of these components can be of interest for different applications considering their antimicrobial or optical properties and will be utilized in further studies. , …”

Effect of Composite Addition of Antibacterial/Photochromic/Self-Repairing Microcapsules on the Performance of Coatings for Medium-Density Fiberboard

“…Bacteria attached to the coating surface can cause damage, leading to a decrease in its protective ability against wooden substrates [25,26]. Adding an active ingredient with an antibacterial effect into the coating can make the coating antibacterial [27] and protect the MDF [28]. The coatings with antibacterial microcapsules can protect the coating and optimize the living environment.…”
