“…The flame retardancy possibilities of PLA have been comprehensively reviewed by Bourbigot and Fontaine, who revealed that the best performance can be provided through intumescence [22], however, the melt dripping is often still an issue. As for a solution, Li et al reported the effective anti-dripping effect of montmorillonite (MMT) clays on PLA matrix when combined with IFR system [23].…”

Impact resistant all-poly(lactic acid) composites were prepared by filmstacking of highly crystalline poly(lactic acid) (PLA) fibres with fully amorphous PLA films. The flammability of the self-reinforced PLA composites (PLA-SRCs) was effectively reduced by incorporating ammonium polyphosphate based flame retardant (FR) additive and montmorillonite clays in a weight ratio of 10 to 1 into the matrix layers. As low as 16 wt% FR content proved to be sufficient for achieving self-* Corresponding author: tel: +36 1/463-1348, e-mail: kbocz@mail.bme.hu, address: Műegyetem rkp. 3., Budapest, 1111, Hungary 2 extinguishing behaviour, i.e. UL94 V-0 rating, and to achieve 50% and 40% reduction of peak of heat release rate and total heat emission, respectively. The introduction of FR additives improved also important mechanical properties compared to the FR-free all-PLA composite. The stiffness of the PLA-SRCs increased steadily with the FR contents of their matrix layers, furthermore, owing to the improved fibre-matrix bonding, prominent energy absorption capacity (impact perforation energy as high as 16 J/mm) was determined for the effectively flame retarded PLA-SRC.

“…challenging task. Various methods for improving the flame retardancy of PLA have already been reviewed by Bourbigot and Fontaine [34]. The authors reported that the incorporation of FRs into polymer through conventional thermoplastic processing is the most straightforward strategy to produce PLA with improved properties.…”

“…This phenomenon will lead to an increase in thermal conductivity, affecting the efficiency of intumescent coating as a heat barrier. On the contrary, C30B acted as an effective synergist in the intumescent coating enhancing the efficiency of APP/MA [34]. Li et al [93] improved the flame resistant properties and melt stability of PLA using IFR (based on ammonium polyphosphate, melamine and pentaerythritol) Chow et al -eXPRESS Polymer Letters Vol.12, No.5 (2018) and OMMT.…”

“…É bem aceito que a melhoria da estabilidade térmica ocorre principalmente devido ao fato de que as camadas de argila dificultam a liberação dos produtos voláteis, provenientes da decomposição [34][35][36] . Os resultados representados na Tabela 3 indicam um efeito contrário ao esperado, com redução da estabilidade térmica, notada pela redução nos valores de T 5% e T máx .…”

Resumo: Neste estudo, foram preparados, pelo método de intercalação do fundido, nanocompósitos de PLA com as argilas organofílicas Cloisite 20A e Cloisite 30B. A influência das argilas no processo de biodegradação do PLA foi avaliada com base no método de respirometria. A incorporação da argila Cloisite 20A praticamente não alterou a curva de mineralização do PLA. O nanocompósito com Cloisite 30B, por sua vez, apresentou um comportamento distinto, indicando um atraso no processo de biodegradação do polímero neste material. As amostras foram caracterizadas pelas técnicas de Difração de Raios X, Análise Termogravimétrica e Calorimetria Diferencial Exploratória. A caracterização dos materiais indicou uma estrutura possivelmente intercalada dos nanocompósitos, bem como a redução da estabilidade térmica e um pequeno aumento no grau de cristalinidade, em relação ao polímero puro.

Study of the Influence from Organoclays on the Biodegradation Process of PLAAbstract: In this study nanocomposites of PLA and organoclays Cloisite 20A and Cloisite 30B were prepared by melt intercalation. The influence from the organoclays on the biodegradation of PLA was evaluated based on the respirometry method. The incorporation of clay Cloisite 20A did not change the mineralization curve of PLA. The nanocomposite with Cloisite 30B, on the other hand, presented a different behavior, indicating a delay in the polymer biodegradation. The materials were characterized by X-ray Diffraction, Thermogravimetric Analysis and Differential Scanning Calorimetry. The materials characterization indicated nanocomposites with an intercalated structure as well as reduced thermal stability and a slight increase in the degree of crystallinity compared to the pure polymer.
