“…In addition, the half crystallization time of different nucleating methods were compared here (SiO 2, 12 PBT/glass fiber, 19 nanoclay, 36 TiO 2, 37 graphene, 38 Pglass, 39 PLA 40 ). The method we reported is superior to those of the traditional methods, implying the effect of sulfonate ionic aggregation (Figure 8).…”

In order to solve the poor nucleation ability and slow crystallization rate of polyethylene terephthalate (PET), we propose a new strategy to prepare PET with self-nucleation ability based on the mechanism of mutual attraction of ions. In this study, a hydroxyl-terminated sulfonate monomer, sulfonated 1,4-butanediol (SBDO) without rigid structure was synthesized as nucleating agent functionalized PET third monomer, and then PET ionomers (PETi) were prepared through melt polycondensation with different contents of SBDO. The half-crystallization time of PETi was sharply decreased in contrast with pure PET and the crystallization temperature was significantly increased from 182.6 C to 210.8 C for PETi1. Due to the high nucleation efficiency of SBDO, the crystallization temperature of PET was significantly increased, avoiding the excessive addition of traditional nucleating agents to deteriorate the mechanical properties of PET. The increased nucleation efficiency was contributed to the aggregation of SBDO induced by the ionic interactions.

“…Örneğin neodimyum (Nd +3 ) katkılanmış fosfat camları günümüzde üretilen en büyük lazer camı olarak bilinmektedir [8]. Ayrıca fosfat camlarının mekanik özelliklerinin mükemmele yakın olması, optik berraklıklarının ve biyo uyumluluklarının yüksek olması nedeniyle hem optik alanında hem de biyomedikal alanında kullanılmaktadırlar [9]. Bütün avantajlarının yanında fosfat camlarının bazı dezavantajları da vardır.…”

Bu çalışmada, yaş kimyasal yöntemi ile üretilen Ba ve Li katkılı sodyum fosfat (NaPO3) camları karakterize edildi. Ba katkılı numunelerin tamamının ve en yüksek Li katkısına sahip numunenin amorf yapıya sahip olduğu görüldü. Bunların haricindeki tüm numunelerin kristal yapıya sahip olduğu gözlendi. Fourier dönüşümlü kızılötesi (FTIR) spektroskopisi sonuçları NaPO3 yapısının oluşumunu desteklemektedir. Morfoloji, katkıların türü ve bunların miktarından etkilendi.

“…The mentioned nucleating agents consist of inorganic fillers (e.g., TiO 2, 6 silica, 7 BaSO 4, 8,9 carbon nanotubes, [10][11][12] graphene, 13 clay, 14 silicon nitride, 15 calcium carbonate, 16 and phosphate glass). 17 To be specific, multi-scale silica has been employed to prepare PET composites. However, it is reported that for considerable defects on the surface of the lower-scale untreated silica, it is easy to cause agglomeration via hydrogen bonds attraction.…”

In the present study, an investigation was conducted on the effects of polyhedral oligomeric silsesquioxane (POSS) on the mechanical, morphological, and thermal properties of PET-based nanocomposites. When the epoxy groups reacted with the PET end groups, the transesterification catalyst zinc acetylacetonate was introduced to facilitate the reaction between PET matrix and EPOSS. As clearly observed in the SEM image, 3 wt% POSS was added to PET matrix, the size of POSS particles was lower than 50 nm. As revealed from the
