Octadecyltrichlorosilane (OTS) and [2-(perfluorooctyl)ethyl]trichlorosilane (FOETS) monolayers their mixed monolayer were polymerized on a water subphase subsequently immobilized onto silicon wafer surface by covalent bonding. Atomic force microscopic (AFM) observation of the (OTS/FOETS) revealed formation phase-separated structure. Protein-adsorption behavior was investigated in situ basis an attenuated total reflection Fourier transform infrared (ATR-FT-IR) spectroscopic flow cell method...
A series of eight aliphatic polycarbonate (PC) glycols with various methylene numbers (HO−[(CH2)mOC(═O)O]n−(CH2)m−OH, m = 3, 4, 5, 6, 7, 8, 9, and 10) were employed as a soft segment for synthesis polyurethane elastomers (PUEs). First all, viscosity, glass transition temperature, melting point, crystalline structure these new PC-glycols investigated. The PC-glycol-based PUEs synthesized using the PC-glycols, 4,4′-diphenylmethane diisocyanate, 1,4-butanediol by one-shot method. Differential...
Polyurethane elastomers (PUEs) containing trans-1,4-bis(isocyanatomethyl)cyclohexane (1,4-H6XDI) have been synthesized by polymerizing 1,4-H6XDI with poly(oxytetramethylene) glycol and 1,4-butanediol. The molecular aggregation state mechanical properties of these PUEs compared those exhibited PUE analogues made MDI diols. hard segment chains in the 1,4-H6XDI-based are found to readily crystallize form strong hydrogen bonds due a high symmetry molecule. Consequently, exhibit well-organized...
A novel diisocyanate, 1,2-bis(isocyanate)ethoxyethane (TEGDI), whose backbone is ether bonds was used for the preparation of polyurethane elastomers (PUEs). 1,6-Hexamethylene diisocyanate (HDI) also as a control. The PUEs were prepared with either TEGDI or HDI, poly(oxytetramethylene) glycol (PTMG), and curing agent by prepolymer method. Differential scanning calorimetry, infrared spectroscopy, wide-angle X-ray diffraction revealed that phase separation network TEGDI-based much weaker...
Liquid crystal elastomers can vary their shape freely with no extra mechanical energy like liquids when deformed in the plane.
Organoclay, such as organo-modified montmorillonite (MMT), is one of the potential filler candidates in preparation epoxy nanocomposite adhesives for automotive and civil engineering industries. However, there no systematic research on effect organoclay reinforcement its adhesion fatigue behaviors shear loading. Here, single-lap joints (SLJs) stainless steel substrates bonded with epoxy/MMT adhesives, consisting diglycidyl ether bisphenol A poly(oxypropylene) diamine various weight contents...
Molecular arrangement of polymerized n-octadecyltrichlorosilane (OTS, CH3(CH2)17SiCl3) monolayer transferred onto hydrophilic substrate by an upward drawing method was investigated with a transmission electron microscope (TEM) and atomic force (AFM). The diffraction (ED) pattern the OTS revealed that molecules were regularly arranged in hexagonal array (10) spacing ca. 0.42 nm. high-resolution AFM image scan area 10 × nm2 exhibited individual methyl group which packing similar molecular...
Abstract A network structure and the mechanical properties, such as stretching adhesive properties of low cross-linking density cured epoxy resin (CER-L), were investigated by swelling test, tensile temperature dependence dynamic viscoelastic properties. CER-Ls synthesized with three different primary monoamines diepoxy. Even though was low, they showed modulus, strength comparable those high-cross linking CER.
Alkyltrichlorosilanes, [2-(perfluorooctyl)ethyl]trichlorosilane (FOETS) and their mixed monolayers were polymerized on the water subphase subsequently immobilized onto silicon wafer surface by covalent bonding. Atomic force microscopic (AFM) observation of [n-octadecyltrichlorosilane(OTS)/FOETS] monolayer revealed that crystalline OTS formed circular domains ∼1–2 μm in diameter surrounded an amorphous FOETS matrix. Lateral (LFM) scanning viscoelasticity (SVM) observations (OTS/FOETS) could...
