“…The calculation is based on that described by Crank 38 for the diffusion through the membranes. This method has been cited in the literature [41][42][43][44] for calculating dissolutionpermeation studies of a mefenamic acid nanosuspension, permeability of dimethyl disulfide, permeation of isoniazid and amitriptyline in chitosan membranes and salicylic acid through skim natural rubber films.…”

The known biotechnological properties of chitosan and the recent biological activities attributed to polysaccharides from Agaricus brasiliensis have been of interest to obtain films constituted by these two polymers. The glucans obtained from the mushroom inhibited about 96.5% of the ferrous ion, besides not promoting a significant increase of lactate dehydrogenase enzyme (LDH), which indicates that the polysaccharide is able to inhibit the production of radical species and also presents low cytotoxicity to the biological systems. The results of spectroscopy analyses in the infrared region (FTIR) and X-ray diffraction suggest an existing electrostatic interaction between the substances. A reduction in the films' swelling capacity was observed with an increase in the polysaccharide content in the composition. In addition, scanning electron microscopy (SEM) revealed greater surface density of the films. In convening the biological properties of the substances, it is expected that this study raises interest in evaluating the films and their capacity for healing wounds and burns.

“…In rubber industries, skim latex isolated from Havea bracileansis (rubber plant grown in Asia) is processed in several steps to produce some row materials like ribbed smoked sheets (RSS), latex concentrate (LC), crepe [1,2]. Natural rubber is used to produce several goods, including tires, glove, shoes, bags, and also for the preparation of slow-release fertilizers [3,4].…”

Lousy odor is severe pollution in natural rubber processing industries and the air pollution treatment by using photocatalytic decomposition method has not much known. This study aims to explore the photocatalyst preparation and characterization of Fe doped ZnO immobilized on fiberglass cloth. Fe doped ZnO was prepared both with and without co-precipitation agent of NaOH. Both methods confirmed the metal existence and gave crystallite catalyst particles with mean diameters of 50 nm according to XRD characterization methods. SEM-EDS analysis showed Fe-ZnO particles prepared without co-precipitation were less aggregated particles than those made with the other method. EDS data identified the elemental composition of Zn, Fe, and O, and the fiberglass cloth composition, including Si and Mg. In the co-preparation method, sodium was always existed along with Fe and ZnO. DR-UV analysis showed the bandgap of Fe-ZnO was 3.20 and 3.22 eV without and with co-precipitation methods, respectively. TEM analysis of the catalyst slurry shows all particles were agglomerated in both preparations. Spherical-like particles existed non-precipitation method, and a spherical- and rod particle shapes were detected in co-precipitation preparation. The non-co-precipitation process was a preparable step in immobilization of the Fe-ZnO particles onto fiberglass cloth

“…However, CNR and skim latex both contained LRP and SRP, making clearcut interpretation of the effect of pure LRP and SRP on latex film properties. An independent study on the pre‐vulcanized mechanism and latex film‐forming process of LRP and SRP individually is expected to reveal the novel features of each and allow possible tuning of the latex film properties with their blends …”

The pre‐vulcanized large rubber particle (LRP) and small rubber particle (SRP) latices are independently prepared to investigate their film‐forming process and mechanical properties after being cast into films. The surface morphologies and roughness of both LRP and SRP films are found to be dependent on crosslink densities. The networks inside each rubber particle (RP) restrict particle deformation resulting in residual contour of RP within the film surface. For highly crosslinked RP, the collapse of the top surface of the RPs in the LRP films appears to create many “crater‐like” structures within the film surfaces, while they present only protruding particles within the SRP and blend films. This seems to indicate that LRPs are easier to coalesce and form film than SRPs. Additionally, dynamic and mechanical properties and strain‐induced crystallization (SIC) behaviors of the latex films, are effectively enhanced after pre‐vulcanization. The pre‐vulcanized LRP films perform better tensile properties and SIC than the SRP can.
