Organic–inorganic hybrid silica film coated for improving resistance to capsicum oil on natural substances through sol–gel route

3-Glycidoxypropyltrimethoxysilan: Description, and Analysis of Works Approaches and Applications

“…In acidic conditions, hybrid halochromic sensor coatings were created by immobilizing Nitrazine Yellow (NY) onto cotton textiles using the epoxy group of 3-glycidoxypropyltrimethoxysilane (GPTMS) silica precursor [57,58]. Boron trifluoride diethyl etherate (BF3OEt2) was employed to catalyze the epoxide ring opening at varied percentages (1-10%, w/w GPTMS).…”

Organofunctional Trialkoxysilane Sol-Gel Precursors for Chemical Modification of Textile Fibres

“…is value is not only lower than the surface tension of water but also lower than the surface tension of oils, such as para n oil, motor oil, and olive oil (y oil ഠ 30 mN/m). In contrast to peruoroalkyltrialkoxysilanes, alkyltrialkoxysilanes cannot provide the oleophobicity of the coating [13,19,40,41]. A low surface energy alkyl-and peruoroalkyl-functionalised coating has been reported to be able to induce additional functional properties, e.g., passive antibacterial activity of the coated bres due to the lowered adhesion of bacteria [13,15,42] and improved anti-icing/de-icing properties of the coated fabric [43] (i.e., the icephobicity because of the low solid-ice adhesion and low shear strength of ice) [44].…”

“…R' represents an alkyl or organofunctional group, and R represents a methyl, ethyl, propyl or butyl group e "so chemistry" or "chimie douce" of the sol-gel processing of hybrid organofunctional trialkoxysilane precursors [9] is an exceptional strategy for environmentally friendly surface functionalisation of textile bres that involves the deposition of thin hybrid lms from the liquid phase [18]. e nanosized thickness of the hybrid polysilsesquioxane network ensures a high optical transparency [19], whereas the inorganic backbone does not in uence the solidstate physical properties of the bres, such as their crystallinity [20]. is process enables the development of novel, upgraded high-performance and durable textile-protective functionalities, such as water and oil repellency, soil repellency, antimicrobial properties, anti-static properties, conductivity and ame retardancy.…”

Effects of starch maleation and sulfosuccination on the adhesion of starch to cotton and polyester fibers

“…Measured values were recorded after 2 s, when the droplet began to still on the substrates. [11,12] Three replicate determinations were performed for each sample, and the result reported were average of these three replicates. Static contact angle images were taken using above system at a camera resolution of 780 × 580 pixels.…”
