Polyethylene Composites

The jute polyethylene composites were developed using the hot-press technique with different fiber weight ratios. Due to the hydrophilic nature of fiber, it exhibited poor interfacial interaction to hydrophobic polymer matrix. In order to enhance the interfacial interaction between fiber and polymer, the benzene diazonium salt (BDS), propionic anhydride (PA), and 3-isocyanatopropyl triethoxysilane (silane) treated jute were used for the manufacturing of composites in this study. The chemical resistance tests of prepared composites were performed in order to probe whether these are resistant to various chemicals such as: acids, alkalis, and solvents. The effect of chemical treatments of the composites have been investigated. It was observed that the fabricated composites were resistant to all chemicals except carbon tetrachloride. The treated jute composites showed higher chemical resistance than raw jute composite and silane treated jute composite yield the highest resistance which can be suggested for making the water and chemical storage tanks.

In this study, jute polyethylene clay nanocomposites were developed using hot press technique. The hydrophilic nature of fiber and nanoclay exhibited poor interfacial interaction to hydrophobic polymer matrix. In order to enhance the interfacial interaction among fiber, polymer, and nanofillers, the chemically treated jute (with benzenediazonium salt, propionic anhydride, and 3-isocyanatopropyltriethoxy silane) and organically modified nanoclay were used for the manufacturing of nanocomposites in this study. The effect of chemical treatments and nanoclay addition on the improvement of absorption characterizations of prepared nanocomposites against water and few chemical reagents have been investigated. It has been observed that the treated jute composites showed higher improvement in absorption properties than raw jute composite and silane treated jute composite found highest value. In addition, nanoclay filled composites showed higher improvement than composite without nanoclay and MMT-1.31PS nanoclay loaded nanocomposite exhibited highest improvement among five types of MMT nanoclay used in this work. The fabricated nanocomposites were resistant to all chemicals used except carbon tetrachloride.

Benzene Diazonium

Five types of selected tropical light hardwoods were chemically modified with benzene diazonium salt to improve their physical and mechanical properties. Benzene diazonium salt underwent a coupling reaction with wood which was confirmed through FT-IR analysis. The compressive modulus of the treated wood increased, whereas modulus of rupture was shown to decrease on treatment. The modified wood samples had higher hardness (Shore D) values compared to that of the control ones.

Polyamide-imide (PAI) and polyurea-amide-imide (PUAI) resins were polymerized from five reactants: 4,4'-oxydianiline, 4-nitrobenzoyl chloride, 4,4'-diphenylmethane diisocyanate, 1,2,4,5-benzenetetracarboxylic dianhydride, and 3,3'-4,4'-benzophenone tetracarboxylic dianhydride. Their chemical structures were characterized using elemental analysis, FTIR and 1H NMR spectroscopy. Their thermal properties, adhesive properties, electrical properties, heat resistance, and chemical resistance were studied. The experimental results show that the glass transition temperatures of PAI and PUAI films occurred respectively at 360 °C and 229 °C, and the 10% weight loss occurred respectively at approximately 481 °C and 420 °C. The optimal hot-press conditions for PAI/copper foil (CU) composite were 380°C and 4.90 MPa, whereas those for PUAI/copper foil (CU) composites were 250 °C and 4.90 MPa. Values of the peel strength, dielectric constant, and dissipation factor were obtained and the peel strength was re-measured after a thermal stability test. The chemical resistance tests showed that the peel strength retention values of the PAI/CU and PUAI/CU composites were respectively more than 95% and more than 94% after immersing in 10% H2SO4 solution at 70 °C for 1 h.

The chemical resistance of Poly-3,4-ethylenedioxythiophene (PEDOT) was tested in both organic and inorganic solvents including Chloroform, DMSO, Xylene, THF, sulfuric acid, sodium hydroxide and sodium chloride. PEDOT was synthesized via the vapor-phase polymerization and coated on PET/cotton, cotton and polyester textile substrates. Electrical resistances of the PEDOT were measured both before and after chemical treatments. The morphological changes after treatments were studied by scanning electron microscope (SEM). The PEDOT coated fabrics demonstrated excellent chemical-resistant property since its electrical resistance maintained on the order of magnitude of 100 ohm after treatment in almost all the solvents except NaOH with which a remarkable increasing of electrical resistance occurred due to disappearing PEDOT from the substrate indicating its potential to be a good solvent for PEDOT.

Amide-containing bismaleimide (ACBI) resins were prepared using four monomeric reactants: 3,4'-oxydianiline (3,4'-ODA), trimellitic anhydride (TMA), maleic anhydride (MA), and 4-aminobenzoic acid. Their chemical structures were characterized using elemental analysis and FTIR. The peel strength, dielectric constant, dissipation factor, heat resistance, and chemical resistance were studied. The experimental results show that the optimal hot-press conditions for ACBI/copper foil laminates was 320 °C and 4.9 MPa. The ACBI laminates treating with 0.2% NZ97 coupling agent had the highest peel strength of 2.097 kN/m. The peel strength was 1.568 kN/m after 24 h at 300 °C. The 1 MHz dielectric constant of ACBI was 3.48, and the dissipation factor was 0.0082. After a hot/wet treatment (steam at 100 °C) for 72h, ACBI laminates maintained 76% of their original peel strength. After treating in 10% H2SO4 solution at 60°C for 30 minutes, ACBI laminates maintained 88% of their original peel strength.

In this study the tropical light hardwood species jelutong (Dyera costulata), terbulan(Endospermum diadenum), batai (Paraserianthes moluccana), rubberwood (Hevea brasiliensis), and pulai (Alstonia pneumatophora) were treated with benzene diazonium salt to improve their dynamic Young’s modulus (Ed), and thermal stability. Benzine diazonium salt reacted with cellulose in wood and produced 2,6-diazocellulose by a coupling reaction, as confirmed by Fourier transform infrared (FTIR) spectroscopy. Values of Ed were calculated from the free-free flexural vibration method and found to increase on treatment. The morphological properties were studied by FTIR and scanning electron microscopy (SEM) and found to be changed. Thermal properties of treated wood samples were evaluated by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The treated wood samples exhibited an increased thermal stability relative to the untreated wood samples; this increase may be related to the formation of 2, 6-diazo cellulose compound.
