The improvement in the insulation material performance is one of recent crucial problems. energy consumption construction and buildings field has a significant impact on society environment. For these reasons, researchers have focused studying their thermal behaviour order to improve fabrication methods design structures. In this sense, great contribution been offered by modeling procedures. A remarkable attention dedicated application fractal geometry which seems be promising method replicate porous structures as well predict effective conductivity. paper, review different procedures presented, comparing both traditional theory-based approaches. Fractal models demonstrate high reliability reproducing experimental data under various conditions, including dry moist systems. This further enhanced recursive formulas, streamline calculations even for complex microstructures. choice between model another depends specific characteristics materials study. all cases, versatility analytical enables achieve agreement with data.

The development of fully renewable and biodegradable composites for short-term applications was pursued by combining a compatibilized poly(lactic acid) (PLA)/poly(butylene succinate-co-adipate) (PBSA) (60:40 wt:wt) blend with coffee silver skin (CSS), an industrial byproduct from processing. An epoxy-based reactive agent (Joncryl ADR-4468) added as compatibilizer. CSS incorporated at 5, 10, 20 wt% in the both as-received state after simple thermal treatment boiling water, which performed to mitigate negative impact this filler on rheological mechanical properties blend. effectively increased degradation temperature 30–40 °C, enabling stable melt processing composites. It also improved filler–matrix adhesion, resulting enhanced (up +172% increase energy compared untreated filler). Therefore, treated demonstrated potential effective green reinforcement PLA/PBSA blends rigid packaging applications. Future works will focus studying suitable surface modification further interfacial interaction tensile quasi-static properties, exploit capabilities material toward eco-friendly

Herein, a hydroxyl-terminated hyperbranched polymer (HPN) with abundant terminal hydroxyl groups was employed to modify straw-plastic composites and studied the effect of HPN concentration on straw fiber reinforced polylactic acid (SF/PLA). Silane coupling agent (CA) used improve interfacial compatibility between SF, PLA matrix. The mechanical strength, thermal properties water resistance different SF/PLA were tested analyzed. When is 6%, HPN-SF/PLA has best strength index. modification, CA modification combination both have positive improving performance. Compared UN-SF/PLA, tensile, flexural impact HPN+CA-SF/PLA increased by 24.7%,16.6% 10.8%, respectively. crystallinity treated HPN, CA, their from 28% 29.4%, 36.9%, 42.3%, However, low melting point caused decrease in Tg, Tm, Tc, Td5% Tdmax SF/PLA. These characteristic temperatures can be enhanced adding for co-modification. In addition, three modified approach able enhance due reduction number SF surface enhancement bonding properties.
