“…It is also referred to as ageing resistance. The main factors influencing bamboo scrimber's ageing resistance are as follows: first is the chemical composition and fibrous morphology of the material; second is the adhesive's water and heat resistance used in the production of bamboo scrimber; and third are external environmental conditions, such as temperature and humidity when used [9,10]. Currently, there is no specialised testing method to evaluate the ageing resistance of bamboo scrimber at home and abroad using some commonly accelerated ageing testing methods.…”

In this study, the six-cycle accelerated ageing method (method I), the 6 h boiling-freezing-drying method (method II), the wet circulation method (method III), and the boiling-testing method (method IV), which are accelerated ageing testing methods, were used to study the ageing resistance of bamboo scrimber. Changes in the nail-holding power of the plane, the side, and the end face of untreated/treated bamboo scrimber were analyzed systematically, including other changes in mechanical properties, such as the horizontal shear strength, the modulus of rupture (MOR), and the modulus of elasticity (MOE) along the smooth grain, etc. The results show that all mechanical properties decreased after treatment with the four accelerated ageing testing methods: the nail-holding power decreased by 4%~42% on the plane, 8%~40% on the side, and 5%~66% on the end face. The horizontal shear strength decreased by 3.1%~16.7%, the MOR decreased by 15%~27.2%, and the MOE decreased by 2.6%~12.8%. The nail-holding power of the three sides and the MOR were the most affected properties after treatment. So, the nail-holding power and the MOR can be chosen as important indices to evaluate bamboo scrimber’s weather resistance. For the four accelerated ageing testing methods, the degree of influence on the nail-holding power was in this sequence: method I > method III > method IV > method II. However, after comprehensive consideration, the degree of influence on the mechanical properties was in this sequence: method I > method IV > method III > method II.

Warm compaction technology is an eco-friendly method to improve the added value of poplar. In this work, the wood powder was compacted in the mold between 120 °C to 200 °C, at 80 MPa for 30 min. The color change, chemical properties, and mechanical properties were evaluated. The color of the formed compaction darkened uniformly. The CIE lightness color coordinate (L*) and chroma coordinates a* and b* decreased with the increase of forming temperature. Fourier infrared spectral analysis showed degradation of carbohydrates, along with the formation of a new chemical structure of darker color. Mechanical properties including modulus of rupture (MOR) and modulus of elasticity (MOE) of compacted wood increased initially and then decreased. These results provide a reference for the surface color control of thermally forming materials.

“…PAN fiber was chosen as a matrix due to its remarkable resistance against UV degradation. 22,23 The co-dispersion solvent can partly dissolve and swell the PAN, and at the same time facilitate the anchoring of P25 nanoparticles onto the PAN fiber surface during the dip coating process. The optimal coating conditions were determined by the photocatalytic performance of the obtained P25-coated fibers.…”

Polyacrylonitrile (PAN) fiber coated with photocatalyst titanium dioxide (P25) was successfully fabricated by a dip coating process using dimethyl sulfoxide (DMSO)/ethanol (EtOH) as co-dispersion solvent. Photocatalytic performance of P25-coated PAN fibers was evaluated by degrading a model dye rhodamine B (RhB) in aqueous solution under ultraviolet (UV) light irradiation. The preparation parameters of P25-coated PAN fibers were optimized by an orthogonal design, and were found to be a P25 concentration of 0.05 g/L, a ratio of 85/15 (v/v) DMSO/EtOH, and a take-up speed of 0.5 m/min. A possible mechanism of co-dispersion solvent dip coating was proposed based on Hansen solubility parameters’ theory. The P25-coated PAN fibers prepared at the optimum conditions had high dye removal efficiency. They also showed an excellent cycling performance for dye removal of up to 99% recovery over several cycles. The coating process has little impact on both the fiber strength and the breaking strength. The breaking strength of P25-coated PAN fibers was maintained even after several cycles. This study provides an easy-to-scale-up method for preparing P25-coated PAN fibers. The obtained P25-coated PAN fibers show great potential as a low-cost, easy handling, and recyclable photocatalyst for dye effluent treatment.
