ABSTRACT This study investigated the thermal and spectroscopic properties of composites produced from Polyamide 12 (PA 12) and montmorillonite (MMT) or sepiolite (SEP) clays, for application in additive manufacturing. These properties are critical during the printing process, as they directly affect the balance between the energy input to the parts and

Organoclays Trap Recalcitrant Metals and Organic Compounds
The capability of organoclays as components of permeable sediment barriers has been researched extensively over the past several years. Organoclays have been used in permeable walls to block the movement of a DNAPL plume from an abandoned wood treating ...

Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Corrosion Protection Enhancement via Rheology‐Optimized Clay‐Reinforced Fluoropolymer Coatings
Organomodified montmorillonite yields a well‐dispersed, high‐tortuosity network in PVDF‐HFP coatings, improving rheology and producing superior barrier performance and adhesion compared to aggregated unmodified montmorillonite. ABSTRACT Poor adhesion and limited barrier performance constrain the corrosion protection efficacy of poly(vinylidene fluoride‐

Surface‐Confined Nanoclays in Ethylene Butyl Acrylate Copolymer: Toward Smarter Flame Retardancy
This paper presents the design and characterization of nanostructured flame‐retardant systems based on ethylene–butyl acrylate and nanoclays. Two different approaches, namely bulk and surface‐coating, were exploited, comparing their effects on combustion behavior, ignition delay, and char formation.
