Through a series of tests, it was determined that the composite film with 2 % BN and 4 % GO exhibited the best piezoelectric effect. The β-phase content increased from 76.01 %, to 98.48 %. The remanent polarization increased from 0.029 μC/cm² to 0. 098 μC/cm², BN and GO synergistically enhanced the piezoelectric effect of P(VDF-HFP) film, the presence of GO induces the transformation of BN from multilayer to monolayer, which breaks the inverse symmetry of BN and thus enhances the piezoelectric effect, and the presence of GO increases the flow of electrons between the nanomaterials. While the B atoms in the BN interact with the F atoms in P(VDF-HFP), which promotes the enhancement of the β-phase in the PVDF-HFP. The piezoelectric film was made into piezoelectric sensor, under a force of 2 N, the piezoelectric output increased from 1.5 V to 7.3 V, the sensitivity increased from 0.722 V kPa⁻¹ to 3.068 V kPa⁻¹. The manufactured piezoelectric sensor exhibits fast response and recovery times (13.66/19.25 ms), after 7000 cycles of testing, the sensor maintained good stability. The developed piezoelectric sensor can detect human motion states, sense the temperature and harvest high-entropy energy to power electronic watches, showing promising potential for applications in smart clothing.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"155 ","pages":"Article 112341"},"PeriodicalIF":4.3,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143850054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, by selecting the corresponding optimal parameters during the initial and prolonged deposition stages, this method ensures that the DLC film exhibits both a high sp3/sp2 ratio and excellent adhesion to alumina. The growth process of DLC on the alumina surface was investigated, revealing that the limited ion energy range is the rationale behind the phased regulation method.

In this study, atomic insights into the graphitization transformation behavior of Ni-catalyzed diamond were investigated in detail through rapid annealing at different temperatures and <em>in situ</em> heating observations using the transmission electron microscope. The results revealed that Ni recrystallized first as the temperature increased. Then, C atoms in the diamond gradually diffused and migrated into the Ni layer, leading to the formation of a metastable C<img>Ni compound. As the temperature-induced migration of C atoms continued, the C concentration in the C<img>Ni compound became supersaturated, resulting in ordered precipitation and forming the graphite layer on the diamond surface.

Using a modified Debye-Callaway model, theoretical calculations are performed for two groups of diamond specimens. The first group comprises single-crystal diamonds with varying nitrogen concentrations, ranging from nearly pure to highly doped specimens. The second group comprises single crystals, microfilms, and nanofilms of varying sizes, allowing for an investigation of size-dependent effects. The study systematically examines the contributions of various phonon-scattering mechanisms, including phonon-phonon interactions (Normal and Umklapp processes), point defects, isotopes, boundary scattering, dislocations, phonon-electron interactions, and phonon resonance scattering for both longitudinal and transverse phonon modes. Notably, phonon resonance scattering plays a significant role in LTC reduction at low temperatures, where phonons interact with localized defect-induced vibrational modes. Nitrogen impurities act as strong scattering centers, significantly disrupting the lattice structure and reducing LTC. The degree of reduction correlates with nitrogen concentration, defect density, and platelet configurations. Crystal size is another critical factor, as smaller samples exhibit enhanced boundary scattering, resulting in a pronounced decline in LTC, particularly at nanoscale dimensions. The work further identifies systematic relationships between LTC, nitrogen concentration, and crystal size, providing key mathematical models to predict thermal transport behaviour.
