Abstract Camellia oleifera is one of the four largest oil tree species in the world, and also an important economic crop in China, which has overwhelming economic benefits. However, Camellia oleifera is invaded by various diseases during its growth process, which leads to yield reduction and profit damage. To address this problem and ensure the healthy growth of Camellia oleifera, the purpose of this study is to apply the lightweight network to the identification and detection of camellia oleifolia leaf disease. The attention mechanism was combined for highlighting the local features and improve the attention of the model to the More >

Abstract In this study, 3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate (ECC) and refined Camellia oleifera seed oil (RCOSO) obtained from saponification and acidified hydrolysis has been used as raw materials to perform ring-opening reactions for the preparation of cyclohexyl acrylate derivative (CAR). The structure of the synthesized product was characterized using infrared spectroscopy, Raman spectroscopy, and nuclear magnetic resonance spectroscopy. CAR was employed as a plasticizer to produce modified polyvinyl chloride (PVC) films, dioctyl phthalate plasticizer (DOP) used in reference samples to investigate the influence of different plasticizer molecular structures on the properties of PVC films. Observation suggested that (1) CAR More >

Abstract Plasticizers are essential additives in the processing of polyvinyl chloride (PVC), with phthalate plasticizers being widely used. However, these conventional plasticizers have been shown to be harmful to human health and environmentally unfriendly, necessitating the exploration of eco-friendly bio-based alternatives. In this study, Camellia oleifera seed oil, a specialty resource in China, was utilized as a raw material and reacted with 4,4′-Methylenebis(N,N-diglycidylaniline) (AG-80) to synthesize Phenyl Camellia seed Oil Ester (PCSOE). PCSOE was employed as a plasticizer to prepare modified PVC films with varying concentrations, with the conventional plasticizer dioctyl phthalate (DOP) serving as a control.… More >

Abstract In this study, as the plasticizer, Camellia oleifera seed-oil-based cyclohexyl ester (COSOCE) was prepared by the reaction of cyclohexene oxide and refined C. oleifera seed oil (RCOSO) obtained by acidification hydrolysis after saponification. In addition, the structure of the target product was confirmed by Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and Raman spectroscopy. COSOCE was used as plasticizer-modified polyvinyl chloride (PVC) membranes. The structure of the COSOCE-modified PVC membranes were characterized by Raman spectroscopy and scanning electron microscopy (SEM). The properties of the COSOCE-modified PVC membrane were characterized by contact angle measurements, universal… More >
