“…expanding under cooling and shrinking under heating leading to the so-called "two-way reversible actuation". 15,77 Besides, the self-healing ability of neat Surlyn® during ballistic penetration was investigated by Varley et al 78 Herein, Surlyn® presents better self-healing and more elastomeric properties above its melting temperature (T m ) due to the high mobility of ions within these ionic clusters. 79 Besides, better healing properties are obtained above the T m by neutralizing the ionomer to a large extent with sodium cations (formation of ionic interactions and ionic clusters).…”

“…Zinc complexes of fatty acids are a class of compounds with interesting structural properties. These so-called zinc soaps find application as fillers/plasticizers in polymers, [1][2][3][4] as stabilizers in polyvinyl chloride (PVC), 5 and as precursors for nanoparticle synthesis. 6,7 However, in the last decade, zinc soaps have also been studied extensively [8][9][10][11][12][13][14] as a degradation product in oil paintings that contain zinc white (ZnO) pigment, one of the most common white pigments used by artists in the late 19th and 20th centuries.…”

The formation of crystalline zinc soaps (zinc salts of fatty acids) in oil paint layers is a common sign of paint degradation. In this study, we have used infrared spectroscopy to systematically identify differences in structure and composition of crystalline zinc soap phases, and report data analysis methods for structure attribution in challenging oil paint samples. Supported by reported crystal structures, it was possible to distinguish two distinct types of zinc soap geometry: a highly symmetrical packing for long-chain saturated soaps (type B) and an alternating packing for zinc soaps with short, unsaturated, or dicarboxylic chains (type A). These two types of packing can be identified by a single or split asymmetric COO stretch vibration band. With this new information, we studied the structure and composition of zinc soaps formed in a zinc white model paint and in a cross-section from the painting Equations in Space by Lawren Harris. Using non-negative matrix factorization, band integration and band position maps, it was possible to clearly identify zinc azelate in the model paint and map its spatial distribution. The same methods showed that the paint cross-section contained both types of zinc soap structure within the same paint layer, with the less symmetrical structure appearing only at the interface with the ground layer. The results give valuable information on the internal chemistry of oil paint layers, and the demonstrated methods can find widespread application for in-depth analysis of infrared microscopy data.

“…The aggregation of ionic groups forms numerous physical cross‐linking clusters, which retards the chain mobility of PBS matrix. Recently, ionomers are favorable for the practical application in commercial fields, such as shape memory materials, 36,37 water absorbing polymers, 38 foams and self‐healing materials 38‐41 . Nevertheless, the research on improving the thermal conductivity of PBS ionomer (PBSI) films is still in its infancy.…”

One of the defect for polymers based film is the low thermal conductivity which restricts their application. In this study, an effective strategy in improving the thermal conductivity of poly(butylene succinate) phosphorus‐containing ionomer [phosphorus‐containing ionic group (PCIG) content was 1wt%, denoted as PBSI1‐K] by compression molding was proposed. PBSI1‐K films with anisotropic thermal transport were fabricated by thermal compression molding with different compression molding pressure (2000, 2500, 3000, and 3500 psi). The relationships between the compression molding pressure and properties, including thermal conductivity, crystallization behavior and chain orientation degree of PBSI1‐K films were investigated. Strikingly, PBSI1‐K film fabricated at 2500 psi pressure, denoted as PBSI1‐K‐2500, achieved 5‐fold increase in in‐plane thermal conductivity when PBS was used as the contrast. The impressive improved thermal conductivity (542 mW m−1 K−1) in horizontal direction are ascribed to the fact that PBSI1‐K‐2500 obtained the large spherulite diameter (517 um) and high chain orientation degree (1.90). Furthermore, we introduced graphene into PBSI1‐K and the thermal conductivity of GNS/PBSI1‐K composites have also been discussed. We hence showcase compression molding here as a facile strategy to prepare ionomer film with improved thermal conductivity. The prepared PBSI1‐K‐2500 can serve as biodegradable films to replace petroleum‐based plastic materials and remedy the pollution of “microplastics.”
