In the present work, we have synthesized zinc oxide nanoparticles by two different methods simple solution route and sol-gel (Z1, Z2). SEM analysis of ZnO nanoparticles samples (Z1 and Z2) showed that, the morphology of samples found to be look like nanorods. Transmission Electron Microscopy (TEM) images showed that the particles are spherical, and the particles size of sample Z2 larger than sample Z1. The partial size of sample Z1 is between 17.61 to 2.81 nm and for sample Z2 was between 25 to 6 nm. Also, thin films of ZnO/Chiosan nanocomposites (Z11and Z21) were prepared to study dielectric and antibacterial properties. Results showed that, the value of the dielectric constant for sample Z11 is less than the value of Z 21, it is may be due to different in particles size according to the space-charge theory (dielectric constant increase with increasing of particles size). Frequency dependence dielectric properties of ZnO/Chiosan thin films (Z11 and Z21) at room temperature were measured. Dielectric constant ε' and dielectric loss ε" for all samples were found to be decrease with increasing frequency.The synthesized ZnO/Chiosan nanocomposite films exhibited activity against Gram-negative Pseudomonas aeruginosa (PA), and Gram-positive Staphylococcus aureus (SA).All results indicated that, the antimicrobial activity of the nanocomposite film samples due to presence of nano ZnO particles.

“…As shown in Figure a, ZnO NPs, synthesized with 4 wt% starch under an ultrasonic irradiation power of 1500 W for 10 min, were granular with indefinite shape. It is possible that ZnO may bind to (via OH groups) and then be trapped inside starch molecules . Figure b displays the particle size of ZnO NPs.…”

Zinc oxide nanoparticles (ZnO NPs) are used as antifungal agents and imparted in starch paste. The zinc oxide nanoparticles are synthesized using starch as a stabilizing agent under sonochemical irradiation, and then used in the preparation of ZnO NPs‐based starch paste. The effects of starch and ultrasonic irradiation on the formation of ZnO NPs are subsequently investigated. Characterization by X‐ray diffraction and transmission electron microscopy reveals that ZnO NPs synthesized under an optimal condition are highly dispersed and well‐defined crystals with diameters of approximately 5 nm. The antifungal performance of ZnO NPs‐based starch paste is evaluated under a high temperature and humidity environment, and is compared with traditional fungicides, alum, and pure terephthalic acid (PTA). In addition, the paste shows negligible toxicity and deterioration to the mechanical properties of the mounted paper. Lastly, the paper mounted with ZnO NPs‐based starch paste shows superior antifungal performance, an essential property protecting paper documents from mold growth, compared to pristine starch paste.

A variety of natural, synthetic, and biosynthetic polymers such as poly(L-lactide), polyhydroxyalkanoate, and poly(ε-caprolactone) are biocompatible and environmentally degradable. Biodegradability can therefore be engineered into polymers by the judicious addition of chemical linkages such as anhydride, ester, or amide bonds, among others. Poly(L-lactide) (PLLA) has attracted increasing attention due to the combination of its bioresorbability, biodegradability, biocompatibility, and shape memory effect. It has been widely applied to biomedical fields such as bone screws, surgical sutures, tissue engineering, and controlled drug delivery. Nevertheless, the PLLA is weaker than that of natural cortical bones in mechanical strength. Additionally, the ability of PLLA in cell attachment and bioactivity are weak due to its hydrophobic properties. In order to overcome the unsuitable properties of PLLA, various techniques have already been applied to modify the physical and mechanical properties of PLLA. The most significant method is to introduce some various kinds of fillers into PLLA matrix to provide reinforcing filler/PLLA composites, such as hydroxyapatite (HA), b-tricalcium phosphate, bioglass, silica gel, amorphous carbon, carbon nanotubes (CNTs), and so on.
