PLA and Montmorilonite Nanocomposites: Properties, Biodegradation and Potential Toxicity

open access: yesJournal of Polymers and the Environment, 2013
The concern related to solid waste increases efforts to develop products based on biodegradable materials. At present, PLA has one of the highest potentials among biopolyesters, particularly for packaging. However, its application is limited in some fields.

Nanocomposites Obtained by Montmorilonite Clay Additivation in P3 (HB-8%HV)

Materials Science Forum, 2014
Modified montmorilonite additivated films of poly 3 (hydroxybutyrateco-8%-hydroxyvalerate) were formulated by solvent evaporation technique and then characterized by means of X-ray diffraction, scanning electron microscopy, atomic force microscopy and scanning differential calorimetry.

Ethylene glycol monoethyl ether adsorption by interlayer montmorilonite-organic matter complexes: Dependence on the organic matter content and its alkyl chain length

Applied Clay Science, 2019
Abstract The ethylene glycol monoethyl ether (EGME) adsorption method is an essential and available technique for measuring the total specific surface area (TSSA) of natural rock samples that usually contain an abundant amount of clay-organic matter (clay-OM) complexes.

Nanocomposites based on montmorillonite and unsaturated polyester

open access: yesPolymer Engineering and Science, 1998
The concept of nanoscale reinforcement provides opportunity for synthesis of new polymer materials with unique properties. Montmorilonite (MMT) was derived from bentonite, purified, activated by sodium ions and mixed with reacting unsaturated polyester ...

Synthesis and characterization of PMMA and organic modified montmorilonites nanocomposites via in situ polymerization assisted by sonication

Applied Clay Science, 2018
Abstract A variety of organo-modified montmorillonite (OMMT) and poly(methylmethacrylate) (PMMA) nanocomposites (CPN) were synthetized by in situ polymerization in a chloroform solution under probe sonication at clay loadings of 3 mass%. A factorial experimental design was used to study the effects of the synthesis variables: Flory-Huggins (F-H ...

Priprema i karakterizacija poli(etilen- oksid)/litijev montmorilonit nanokompozita

2011
U ovom radu istraživao se utjecaj dodatka litijevog montmorilonita (Li-MMT) na kristalnost, toplinska svojstva (staklište, talište) i toplinsku postojanost poli(etilen-oksida) (PEO). Li-MMT je pripremljen procesom ionske izmjene iz prirodnog montmorilonita.
