Poly(caprolactone) Enabled Ultralight and Recyclable Poly(butylene adipate-co-terephthalate) Foams for Thermal Insulation Application

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(35), P. 13231 - 13243

Published: Aug. 22, 2024

Biodegradable thermal insulation foams are drawing widespread attention due to the growing environmental pollution and energy waste. Polymer-based characterized by flexibility, recyclability, excellent insulation, hold immense promise for application domains aimed at decreasing Poly(butylene adipate-co-terephthalate) (PBAT) has been widely employed in terms of its superior mechanical properties acknowledged biodegradability. However, owing poor foamability inherent shrinkage PBAT, it is still challenging prepare high-performance PBAT with insulation. Herein, biodegradable polycaprolactone (PCL) crystalline particles were introduced into matrix. High strength recyclable multifunctional prepared physical foaming process. The presence PCL can improve crystallization promote formation open-cell structures. Thanks heterogeneous nucleation special structure, achieved PBAT/PCL foam shows ultralow density (0.04 g/cm3), restricted ratio (<5%), enhanced capacity (32.5 mW/m·K), good hydrophobicity (106.0°). More importantly, compared other degradable polymer foams, degradation ability soil. Our method offers a novel alternative producing environmentally friendly, recyclable, without worries regarding biodegradability that linked nondegradable materials.

Impact-Resistant PLLA/PBAT Composites Based on Novel Biobased Reactive Microcross-Linked PBAT

Industrial & Engineering Chemistry Research, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 8, 2025

Due to the differences in molecular structure, Poly(L-lactide) (PLLA) and Poly(butylene adipate-co-terephthalate) (PBAT) are inherently immiscible melt processing, resulting limited mechanical properties of PLLA/PBAT blends. Herein, a novel biobased microcross-linked PBAT has been prepared through dynamic vulcanization presence dicumyl peroxide (DCP) cardanol glycidyl ether (CGE). The rheological behavior showed that modified exhibited high complex viscosity storage modulus comparison virgin due formation cross-linking structure. When contents DCP CGE were, respectively, 1.0 2.0 wt % compared PBAT, degree named B/1.0D/2.0C reached maximum 37.1%. At aid this notched impact strength elongation at break blend PLLA 10.0 kJ/m2 265.4%, about 1.8 times pristine L/B toughening effect was attributed enhanced improved interfacial interaction between PBAT. simulation results further confirmed had better miscibility for Thus, work paved new way preparation fully biodegradable impact-resistant PLLA-based composites.

ABSTRACT The curing energy consumption of traditional phenolic resin (PF) is high, and rapid modification required. mechanism also requires further investigation. In this work, the reaction process functional application curing‐accelerated modified resins are studied. Phenol‐resorcinol‐formaldehyde (PRF) resin, sodium bicarbonate‐accelerated PRF (PRF‐SB) zinc oxide‐catalyzed high‐ortho‐phenol‐resorcinol‐formaldehyde (HOPRF) synthesized via in situ polymerization. addition resorcinol oxide increases number active sites molecules reduces activation required for curing. Compared with PF, HOPRF reduced by 9.78%. Sodium bicarbonate crosslinking density resin. kinetics analyzed using Starink Málek methods. results show that involves a combination nth‐order autocatalytic reactions. competition synergy these reactions enhance rate addition, under same conditions, tensile shear strength PRF‐SB 2.88 times PF. lower temperature stronger mechanical properties make have potential wood, casting, other industries.
