“…Polymer nanocomposites are a class of hybrid materials, which have generated a great interest in research and industry, due to their potentially novel properties, which are not existent in other materials . They have found many applications in a wide range of industries, such as automotive, civil construction, sport and aerospace in recent years.…”

Effect of “Z” factor for strength of interphase layers on the tensile strength of polymer nanocomposites

The influences of “Z” factor for the strength of interphase layers on the tensile strength of polymer nanocomposites and various interphase properties are explained applying three approaches including developed Leidner‐Woodhams, Pukanszky, and Callister‐Rethwisch models. All models and equations for interphase parameters are developed based on a multi‐layered interphase in different polymer nanocomposites. The calculations reveal that the role of “Z” factor is highlighted when much volume fraction of nanofiller ( ϕnormalf) is used attributed to the high probability of nanoparticles agglomeration and poor interfacial properties in this condition. However, both “ ϕnormalf” and “Z” parameters positively affect the tensile strength. Additionally, the highest values of interphase properties including “B” in Pukanszky and “s” in Callister‐Rethwisch models are achieved by the high levels of nanofiller strength and “Z” factor.

“…Modification of DMAEMA through the amino group leads to the formation of ammonium salt, which can be used as organomodifier in many polymer/clay nanocomposites preparation . Our previous work depends on the synthesis of intercalated poly( N , N ‐dimethylaminoethyl methacrylate)/clay nanocomposites via solution‐intercalation method . This work aims to prepare exfoliated poly( N , N ‐dimethylaminoethyl methacrylate)/clay nanocomposites via in‐situ bulk polymerization method.…”

Poly(N,N‐dimethylaminoethyl methacrylate)/clay nanocomposites (4a–c) were prepared by in‐situ bulk polymerization method. N,N‐Dimethylaminoethyl methacrylate (DMAEMA) was alkylated using hexyl bromide to afford quaternary ammonium salt (2) which was used in the organomodification process of the clay. The organoclay (3) was dispersed in the DMAEMA monomer at concentrations 1, 3, and 5 wt% and bulk polymerization reactions were conducted to prepare nanocomposites (4a–c), respectively. The prepared nanocomposites were characterized by Fourier transform infrared, X‐ray diffraction (XRD), high‐resolution transmission electron microscopy, and thermogravimetric analysis. The XRD results showed that the polymer/clay nanocomposites have an exfoliated structure. Optical, dielectric, and mechanical properties were also investigated. The prepared polymer (PDMAEMA) film showed a transparency of about 88% and it slightly decreased to 80% for PDMAEMA/clay (5 wt%). The films showed indirectly allowed transition and the optical band gap of the films was evaluated. The dielectric properties of polymer and polymer nanocomposites were discussed. POLYM.

“…In addition, a sharp band corresponding to the Si-O-si stretching vibration of the layered silicate is observed at 1009-1024 cm -2 and the si-O-si and Al-O bending vibration bands are located at 573 and 444-424 cm -1 . [19] Moreover, FTIR spectra of polymer/clay/drugs nanocomposites showed more additional absorption bands compared with that of the neat clay. the spectra of SCACA/ MSB / DOX nanocomposites ( Figure 1b) show the absorption bands of 3750-3100 cm -1 due to N-h stretching vibrations for the primary amine structure and 2924 cm -2 for C-h stretching vibrations.…”

S yNthesIzeD starch cellulose acetate coacrylate (SCACA)/ Sodium bentonite modified Tween-80 (MSB) nanocomposites holding anticancer drugs like 5-fluorouracil (5-FU), Doxorubicin hydrochloride (DOX), and Chlorambucil (CA) as controlled release systems were evaluated and assessment as antiproliferative activity towards breast cancer cell lines, and antimicrobial activity against some strains. the nanocomposites loaded drugs characterized by Zeta Potential, FTIR, SEM and TEM. The results indicated that no change in the chemical structures and physical properties of the drugs into the nanocomposites. the surface texture of the samples was homogenous and smooth with no evidence of aggregations after release and there were some pore like structure and cracks formed due to blooming of drug outside nanocomposites. the particle size diameter of the prepared polymer was found to be 73 ~ 79 nm. After holding Doxorubicin the particle size was from 18 to 24 nm , 5-fluorouracil from 15 to 18 nm and Chlorambucil was from 24 to 75 nm. the release of drug was measured spectrophotometrically. the values of drug released depend on the type and nature of drug as well as the environmental aqueous media. the release in alkaline and acidic media was more faster and higher than that in the neutral one. the invitro study results of anticancer drugs released from polymers placed inside the culture media, showed 5-FU was given an effective promising results compared to DOX and CA. The antimicrobial test revealed that, the released 5-FU gave the highest effect as antimicrobial against all tested strains followed by DOX and CA.
