However, its film material still has some practical problems such as insufficient adhesion and poor high temperature resistance when it is used as the supporting film or bonding layer of FCCL. A novel diamine monomer 4-(p-hydroxyphenyl)-2,6-bis(p-aminophenyl) pyridine ( p,p -HAPP) containing pyridine heterocyclic structure and bulky phenol side-group at its para position was firstly synthesized, and subsequently employed as the second diamine monomer to prepare a series of PI resins by co-polycondensation with ODA and BPADA via the conventional two-step method. Then, the corresponding PI film was prepared by casting the purified PI solution on glass plate, and finally used to prepare flexible copper clad laminate (FCCL) by hot pressing. The chemical structure, composition and purity of p , p -HAPP, as well as the chemical and phase structures of the resulting PIs are confirmed by relevant means. It is found from the following tests that by introducing a certain amount of p , p -HAPP as a second diamine monomer for ternary copolycondensation, it not only ensures that the resulting PIs (PI-1 ∼ PI-3) have good solubilities and relatively low dielectric properties, but also improves their heat resistance, thermal stabilities, thermal dimensional stabilities, mechanical properties and hydrophobicities. In addition, from the tests of FCCL resulted by the preferred PI films (PI-0 ∼ PI-3), which have good comprehensive performance, it is also found that the average peel strength (PS) value of the FCCL, prepared by PI-1 with a 25% molar content of p , p -HAPP in mixed diamines, is up to 1.23 N mm −1 , and the solder float resistance tests at 288°C and 310°C are all passed. Therefore, PI-1 is a good candidate material for interlayer dielectric application of FCCL without requiring any alloplastic adhesion promoter in this study, which provides an effective strategy for the preparation of thermoplastic PI film with excellent comprehensive properties such as excellent solubility, good mechanical property, low water absorption rate ( WAR ), high adhesion and heat resistance.","PeriodicalId":12932,"journal":{"name":"High Performance Polymers","volume":"37 5","pages":"271-285"},"PeriodicalIF":0.0,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147910793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the traditional PAEK has some limitations in processing, such as high melt viscosity and high energy consumption. This study successfully synthesized a series of PAEK copolymers with bisphenol A and phenolphthalein side groups through nucleophilic polycondensation, aiming to reduce the high energy consumption associated with material processing. By adjusting the ratio of bisphenol A to phenolphthalein side groups, this research explores their influence on the properties of the copolymers. Comprehensive characterization using various testing methods revealed that increasing the bisphenol A content led to a decrease in heat deflection temperature and glass transition temperature. Although mechanical performance showed a slight decline, it remained comparable to other advanced engineering materials. Notably, tuning the ratio of bisphenol A to phenolphthalein significantly improved the melt rheological properties of the copolymers, reducing melt viscosity, enhancing polymer chain flexibility, decreasing crosslinking tendencies, broadening the processing window, and lowering energy consumption. This study provides a novel strategy for tailoring the performance of PAEK copolymers, offering substantial potential for further research and application. These copolymers are good candidates for next-generation high-performance engineering plastics.","PeriodicalId":12932,"journal":{"name":"High Performance Polymers","volume":"37 4","pages":"240-251"},"PeriodicalIF":0.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147914775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Refractive index (RI) is one of the properties commonly used to compare the optical properties of materials. The higher the refractive index, the thinner the lens made of the corresponding material; however, the preparation of high-refractive-index polymers is currently a thorny issue, in which the structure of the polymer molecules has a great impact on their refractive index, to design high-refractive-index materials requires starting from the structure of the molecules. Phenolphthalein has a unique structure with a molecular skeleton consisting of three benzene rings and a cyclic lactone that exhibits a twisted non-coplanar structure. This cyclic side group can hinder the accumulation between the polymer molecular chains, not only improving the solubility of the polymer molecules, but also increasing the transparency of the polymer films. In this work, we used phenolphthalein (PHT) and its derivatives to polymerize with terephthaloyl chloride (TPC), respectively, through the structural differences between them, the influence of polymer structure on the refractive index and thermal properties was discussed. Among them, polyester PAR-NPHT had the highest refractive index ( n d >1.67), and is expected to be a new generation of optical materials.","PeriodicalId":12932,"journal":{"name":"High Performance Polymers","volume":"37 3","pages":"191-200"},"PeriodicalIF":0.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147913080","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a silicon-phosphorus blended resin (ED./EB) was synthesized using 10-(2,5-dihydroxy phenyl)-10-hydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-HQ) and hydroxyl-terminated silicone oligomer (Z-6018) as precursors. In comparison to epoxy resin (E−51), experimental results indicated a 16.7% increase in the tensile strength of ED/EB and a 20.7% increase in impact strength. The enhancement and toughening of the resin were simultaneously achieved through the silicon-phosphorus synergistic modification. The flame retardancy test indicates that ED./EB combines the outstanding smoke suppression of silicone modified resin (EB) with the high LOI of phosphorus modified resin (ED-27), while also decreasing the flame growth index (FIGRA) of the resin. After undergoing combustion, the silicon-phosphorus collaboration within the ED/EB material yielded a dense protective covering on the surface. This covering effectively governed the emission of smoke particles and heightened the residual mass.

SEM shows that the modified CSW is uniformly dispersed in the resin. The storage modulus of composites increased from 2.6 GPa to 3.8 GPa. Under air and nitrogen atmospheres, the T 5% of the composites increased by about 10°C. When the addition amount of CSW is 10%, the friction coefficient of the material is reduced from 0.68 to 0.58, the depth of wear marks decreased from 49.1 μm to 27.9 μm, the wear rate of AFPN-10 (the addition amount of CSW is 10%) decreases from 3.59 × 10 −4 mm 3 /(N·m) to 2.70 × 10 −4 mm 3 /(N·m), the wear resistance performance was significantly improved. With the increase of CSW in composites, the hardness, reduced modulus and elastic recovery rate are also gradually increasing, the highest reduced modulus and hardness are 2434 MPa and 597 MPa respectively. The addition of CSW can improve the mechanical properties and thermal properties of the phthalonitrile resin, as well as enhance its anti-friction ability.

Thermogravimetric analysis indicated that the incorporation of Salen-PZN-Ni@Co-MOF significantly enhanced the thermal stability of the EP composites. The existence of Salen-PZN-Ni@Co-MOF enhanced both the vertical burning rating and resulted in a higher limiting oxygen index.
