“…Starch‐nano clay films (Figure B) showed continuous matrices, and the clay particles are shown on the film surface. The obtained images were almost similar to the obtained SEM images by other authors . Starch‐nano clay‐methyl orange and SCBG films (Figure C,D) are almost similar to the starch‐nano clay film.…”

In this work, new composite film based on starch and nano clay particles was provided. The nano composite film was loaded by methyl orange (MO) and bromocresol green (BG) indicators. Two type films, including starch‐nano clay‐methyl orange (SCMO) and starch‐nano clay‐bromocresol green (SCBG) were provided. Some properties of provided films, including solubility in water, moisture uptake, water vapor permeability, FT‐IR, and scanning electron microscopy were studied. According to the results, MO and BG were loaded between starch and nano clay particles physically and clay particle size was between 40 and 100 nm. Finally, the SCMO and SCBG simultaneously were improvised in the milk bottle. According to the color change of indicators in the different pH (MO [3.1‐4.4] and BG [3.8‐5.4]), the fabricated films were used for determination of milk spoilage in a milk bottle. The best advantage of fabricated SCMO and SCBG films is that the indicators do not release into the milk by exposing with the milk. The milk pH is changed during the storage time (from 6.7 to the 4), and in the low pH, the milk is spoiled so the fabricated film smartly could show the spoilage of milk by color changing.

“…The obtained images were almost similar to the obtained SEM images by other authors. 9,19 Starch-nano clay-methyl orange and SCBG films ( Figure 4C,D) are almost similar to the starch-nano clay film. It can be said that the methyl orange and BG dyes have no important effects on the starchnano clay surface structure.…”

“…Therefore, it is of great interest to keep the share of nanoparticles in the selected adhesive as small as possible. According to previous studies, it is possible to achieve the best performance of selected PMCs with a smaller share of SiO 2 or TiO 2 nanoparticles (1%) [16] compared to NC (4%) [18] and CNFs (10%) [19]. Considering the fact that the results of conducted studies are not related to PVAc adhesive systems and mutually differ, higher increase in mechanical strength of adhesives can be achieved with SiO 2 nanoparticles than NC or CNFs.…”

Enhancement of Polyvinyl Acetate (PVAc) Adhesion Performance by SiO2 and TiO2 Nanoparticles

et al. 2019

Post press processes include various types of bonding and adhesives, depending upon the nature of adherends, the end use performance requirements and the adhesive bonding processes. Polyvinyl acetate (PVAc) adhesive is a widely used adhesive in the graphic industry for paper, board, leather and cloth. In this study, the enhancement of PVAc adhesion performance by adding different concentrations (1%, 2% and 3%) of silica (SiO2) and titanium dioxide (TiO2) nanoparticles was investigated. The morphology of investigated paper-adhesive samples was analyzed by SEM microscopy and FTIR spectroscopy. In addition, the optimal adhesion at the interface of paper and adhesive was found according to calculated adhesion parameters by contact angle measurements (work of adhesion, surface free energy of interphase, wetting coefficient). According to obtained surface free energy (SFE) results, optimum nanoparticles concentration was 1%. The wettability of the paper-adhesive surface and low SFE of interphase turned out as a key for a good adhesion performance. The end use T-peel resistance test of adhesive joints confirmed enhancement of adhesion performance. The highest strength improvement was achieved with 1% of SiO2 nanoparticles in PVAc adhesive.

“…Although modifications in the chemistry of wood adhesives are a path of optimization of performance properties, the addition of filler presents a possible alternative route of modification [18] [19] [20]. Another alternative to alleviate the shortcoming of PVAc adhesive is the use of nanoparticles such as carbon nanotube [21] on physico-mechanical properties of PVAc, clay [22] to improve the bonding strength of PVAc, graphene [23] to improve PVAc strength and toughness, cellulose [24] to see the effects of filler on thermal stability [22] to improve the performance of PVAc at elevated temperature and high humid condition. These particles were shown to have a beneficial effect on the properties of PVAc wood adhesives [25].…”

Polyvinyl alcohol (PVA) colloid stabilized Polyvinyl acetate (PVAc) based wood adhesive has poor performance in highly humid conditions. Currently, the addition of natural fillers in the wood adhesive is one of the most effective ways to enhance the performance of PVAc wood adhesive in highly moist conditions. Microcrystalline cellulose (MCC) are strong renewable, bio-based material and has great potential in a reinforcement of the polymeric matrix. Hence, the present work investigates the applicability of microcrystalline cellulose incorporated 3% and 5% in situ emulsion polymerization PVAc wood adhesives. Effect on physical, thermal and mechanical properties was studied by viscosity, pH, contact angle measurement, differential scanning calorimetry (DSC) and pencil hardness test of films. Emulsions with different proportions of MCC were prepared and the shear strength of the applied adhesive on wood was measured. The viscosity of the adhesives was increased by increasing the concentration of MCC. The mechanical properties like tensile strength of adhesives with MCC were measured by universal tensile machine (UTM). Thermal stability was studied by differential scanning calorimetry (DSC). The tensile shear strength demonstrates that MCC can improve bonding strength as compared to PVAc Homo based adhesive in the wet condition which was validated through a contact angle study. The hardness of PVAc films were also changed positively by the addition of MCC. Here, we studied the effect of the addition of different concentrations of MCC materials in situ polymerization of PVAc on their performance properties.
