When the TCA content in the IFR was 35 wt% to 45 wt%, the IFR had good expansion properties. Then, different proportions of IFR were incorporated into polypropylene (PP) to prepare flame retardant PP composites, and the flame retardancy, thermal degradation behaviour and flammability behaviour for PP composites were investigated by limiting oxygen index (LOI), vertical burning test (UL-94) and cone calorimeter test. When 20 wt% of IFR (With TCA 35 wt%) were added into the PP matrix, the composite achieved a V-0 rating for the UL-94 test and its LOI value was increased to 28.8%. Compared with neat PP, peak heat release rate (PHRR) and total heat release (THR) decreased from 827.30(KW·m−2) and 120.48(MJ·m−2) to 210.50(KW·m−2) and 75.08(MJ·m−2).","PeriodicalId":18235,"journal":{"name":"Materials Research Innovations","volume":"9 1","pages":"537 - 547"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74718098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The maximum elongation at break of modified phenolic resin was higher by about 271% than that of pure phenolic resin. Toughness of modified phenolic resin was greatly improved through triolein treatment by bringing in the methylene, ester bond and aliphatic long chains.

Despite the immense research interest attracted by PSCs, their rooftop application remains constrained by their low efficiency and hysteretic nature. To address these issues, in this paper, the introduction of silver metallic nanoparticles (AgNPs) with plasmonic effect was achieved by an experimental approach to stimulate the generation and transport of charge carriers, which subsequently results to minimal hysteresis and broadband-enhanced plasmonic devices. Due to the far-field light scattering effect, AgNPs improve the light-trapping of the devices. As a result, electrical characteristics and light absorption are significantly enhanced, leading to broadband increase in photovoltaic performance. With the introduction of one coating cycle of AgNPs, the highest power conversion efficiency (PCE) of the perovskite solar cells increases from a reference value of 4.543 to 10.856%. The fill factor (FF) of such a device was 0.650, the current density (J sc) was 18.998 mA/cm2, and voltage (V oc) was 0.879 V. This device shows an improvement of ~139.0% in PCE, ~61.7% in FF, ~43.7% in J sc and ~2.8% in V oc over the pristine device that lacks AgNPs. The findings of this study contribute to further insight and understanding of plasmonic PSCs by offering useful references and recommendations for PSCs with noble metal NPs incorporation.","PeriodicalId":18235,"journal":{"name":"Materials Research Innovations","volume":"1 1","pages":"521 - 536"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77277548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
