Nanocomposites are a new material discovery in the 21st century. One of nanocomposite materials which useful life is epoxy-clay nanocomposites. Epoxy clay nanocomposites have reasonably wide application industrial fields such as aerospace, defense, automobile, etc. The purpose writing this review to conduct literature on mechanical properties various Cloisite filler Epoxy-clay Nanocomposites. T...
Higher solid contents (20 % and 40 %) nanocomposites of poly (styrene-co-butyl acrylate) including higher content of Cloisite 30B (7 wt% and 10 wt %) were prepared via miniemulsion polymerization. Stability of the final latexes proved outstanding combination of polymerization procedure and surfactants. Morphological studies revealed by TEM, SAX and XRD showed three structures of core-shell, arm...
Tapioca starch, poly(lactic acid) and Cloisite 30B nanocomposites foams, with clay contents of 1, 3, 5 and 7% (w/w), were prepared by a meltintercalation method. Multiple inputs single output models were developed to predict radial expansion ratio, unit density, bulk compressibility and spring index of the nanocomposite foams. An individual ANFIS model was developed for each mechanical property...
Development of antibacterial and antibiofilm surfaces is in high demand. In this study, nanocomposite of Poly (ε-caprolactone)/Cloisite 30B was prepared by the solvent casting method. The membranes were characterised by SEM, AFM, and FTIR. Evaluation of water uptake, antimicrobial, antibiofilm, and microbial barrier properties demonstrated a significant antimicrobial and antibiofilm activity ag...
نانوذرات خاک رس به علت دارا بودن ویژگی های خاص از جمله نسبت منظر بالا و امکان اصلاح سطح آنها، در سال های اخیر به منظور ساخت نانوکامپوزیت های لاستیکی، بسیار مورد توجه قرار گرفته اند. این در حالیست که کیفیت پراکنش این پرکننده ها در بستر لاستیکی و چگونگی ساختار نهایی نانوکامپوزیت ها می تواند بر روی بسیاری از خواص از جمله سینتیک پخت و همچنین خواص ویسکوالاستیک غیر خطی بسیار موثر باشد. به منظور تهیه ...
high solid content poly (styrene-co-butyl acrylate) latex ( with 20% and 40% solid content) including high amounts of cloisite 30b (7 wt% and 10 wt%) were kinetically investigated. gravimetric method via measuring the rate of polymerization, number of particles and average number of radicals per particle was used. results showed that by increasing the solid content; the average diameter of poly...
آلیاژ پلی کربنات/ پلی بوتیلن ترفتالات نمونه ای از آلیاژهای دوتایی با محدوده وسیعی از کاربردها می باشد اما سختی پایین، استفاده از آن در بعضی کاربردها را محدود ساخته است که میتوان با افزودن ذرات نانو رس آنرا بهبود داد. در این تحقیق نانوکامپوزیت بر پایه pc/pbt و سه نوع نانورس cloisite 15a ، cloisite 20aو cloisite 30b توسط روش اختلاط مذاب تهیه شدند. هدف از این مطالعه بررسی رفتار مورفولوژیکی و رئول...
The increasing environmental pollution with petroleum-based plastics has advanced research on biodegradable polymers. Thermoplastic starch (TPS) is one promising candidate due to wide availability from various renewable sources, low cost and biodegradability. However, TPS significant shortcomings, as high water sensitivity mechanical properties. An approach overcome these drawbacks adding nanof...
A series of novel polyurethane network/organoclay nanocomposites (PUN-NCs) with different soft segment contents (30–60 wt%) was prepared by in situ polymerization solution and characterized. PU network (PUN) made from poly(dimethylsiloxane)-based macrodiol as the 4,4′-methylenediphenyldiisocyanate hyperbranched polyester third pseudo generation hard segment. Nanocomposites were obtained dispers...
