This systematic literature review aims to study the thermal properties (TP) of poly(acrylic acid)-based hydrogels (PAA) by differential scanning calorimetry. The data sources were obtained from Google Scholar via Publish or Perish software 2018 2020. synthesis results show that most analysis TP in PAA-based hydrogel consists glass transition temperature ([Formula: see text]), melting and enthalpy text]). subsequent is important for a new development depth future application.

Poor bonding with its accompanying matrix remains the major factor that inhibits widespread use of natural fiber as filler for composite materials. Recent literature has suggested this matter can be addressed by applying fillers in nanometer size. Thus, present study is carried out to investigate effects incorporating rattan powder nanoparticle size into polypropylene (PP) on thermo-physical properties. Production methodology nanoparticle, particle analysis, morphological study, and thermal...

The objective of this study was to investigate the effect alkali-washing with different sodium hydroxide concentrations on chemical compositions steam-treated Betung bamboo strand. Strands were subjected steam treatment at 126 °C for 1 h under 0.14 MPa pressure and followed by washing 1-5% solution 30 sec. alteration structural non-structural components content strands evaluated. Steam treatments various considerably reduced extractive strands, cell wall strand in small degree. FTIR analysis...

The anatomical characteristics in the culms of four promising Indonesian bamboo species, including Dendrocalamus asper, giganteus, Bambusa vulgaris var. vulgaris, and striata, were investigated to produce an identification key quality indices for further effective utilization. crystalline properties culm determined using X-ray diffraction analysis. asper striata showed vascular bundle type IV, while giganteus displayed III. density increased from bottom top part was higher outer than inner...

Abstract Chemical components content of seven Indonesian bamboo species were investigated. Bamboo used in this study including Andong ( Gigantochloa pseudoarundinacea ), Tali G.apus Hitam G. artoviolacea Betung Dendrocalamus asper Sembilang D. giganteus Ampel Bambusa vulgaris var. and Kuning B. striata ). Holocellulose, alphacellulose, Klason lignin, acid-soluble extractives content, pH value determined. The highest holocellulose alphacellulose found bamboo, respectively. has the lignin...

Exploration of natural resources as composite fillers is still under intensive investigation.

This work prepared biocomposites formulated from recycled acrylonitrile butadiene styrene (ABS) reinforced by nano powders or long fibers oil palm empty fruit bunch (OPEFB). Composite in terms density, Fourier transform infrared spectroscopy, surface...

The performance of helmet prototypes fabricated from acrylonitrile butadiene styrene composites filled with oil palm empty fruit bunch fibers was evaluated. were produced using a milling procedure, while the single-screw extrusion. physical characteristics fibers, which are water content, size, and density, investigated. In addition, mechanical properties helmets, including shock absorption, yield stress, frequency, head injury criterion (HIC), examined. impact strength helmets increases...

The fibers of oil palm empty fruit bunch (OPEFB) stalks were investigated to determine the changes in their basic properties after oven-heat treatment. treatment was conducted at 100 °C or 190 for 15 min. There slightly noticeable morphological, chemical, and thermal alterations treated OPEFB stalk short duration. Scanning electron microscopy (SEM) revealed that had smooth surfaces irregular heavy deposition cementing agents. highest cellulose content (41.68%) present min, whereas...
