However, the main problem of these composites is the agglomeration of nanoparticles which influences the worst dispersion in the epoxy matrix and leads to poor properties of the composite. Therefore, this work aims to study the effect of nanoparticle additions, i.e. ZrO2 nanoparticle and SiO2 nanoparticle including waste glass powder (WGP) which is an alternative inorganic filler, on properties of the epoxy resin-based nanocomposite. The particle surface of each filler was also modified with 3-glycidoxypropyltrimethoxysilane (GTPMS) in order to achieve better dispersion in the disk-shaped bulk composites. The chemical property of modified fillers was characterized by Fourier transform infrared spectroscopy (FT-IR). The physical properties, mechanical properties, water absorption and corrosion resistance of all composites are then investigated. The results revealed that the incorporations of ZrO2, SiO2, and WGP with GPTMS surface modification into epoxy resin-based nanocomposite exhibit better performance in mechanical properties, water absorption and corrosion resistance than the unmodified surface of ZrO2, SiO2, and WGP additions. Although, both modified- and unmodified surfaces of fillers for the epoxy resin-based nanocomposites show improvement in all properties compared to the neat epoxy resin but the electrical properties of epoxy resin-based nanocomposites with unmodified fillers and GPTMS-modified fillers do not show a significant effect on any electrical properties.Keywords: Surface modificationGTPMSepoxy resinnanocomposites Disclosure StatementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work is supported by National Research Council of Thailand (NRCT), Nanotechnology and Material Analytical Instrument Service Unit (NMIS), College of Materials Innovation and Technology and King Mongkut’s Institute of Technology Ladkrabang.","PeriodicalId":13686,"journal":{"name":"Integrated Ferroelectrics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135246433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aims at the preparation of natural silk in the form of silk fibroin (SF) film for utilization in TENG and further improving its output efficiency by embedding organic-piezoelectric gamma-glycine (γ-gly) amino acid to be a hybrid-organic piezoelectric/triboelectric nanogenerator (HO-P/TENG). The attenuated total reflectance infrared spectroscopy (ATR-IR) results demonstrated the N-H, C = O, and C-N bonding for SF and SF/γ-gly, confirming its dominant effect with a strong electron-donating tendency from those amino groups. The scanning electron microscope (SEM) and synchrotron radiation X-ray tomographic microscopy (SR-XTM) images show good dispersibility of incorporated γ-gly on the surface and also inside the SF matrix relating to its content to improve the electrical performance homogeneously. By fabricating the device in the vertical contact-separation mode, the present SF/γ-gly HO-P/TENG at 15 wt% provides the maximum output voltage (VOC) and current (ISC) of 81 V and 121 μA with a maximum output power (Pmax) of 205 μW at the external load resistance of 5 MΩ.
