“…In addition to PPC blends with biodegradable polymer, there are few studies conducted on PPC blends with non-biodegradable polymers (Table 4). For example, poly (methyl methacrylate) (PMMA) [205][206][207], poly(ethylene-co-vinyl acetate) (EVA) [208], polystyrene (PS) [209], urethanes [210], epoxy [112], polypropylene (PP) [211], and bisphenol A (BPA) [212]. The goal of blending PPC with non-biodegradable polymers is to tailor the properties of PPC (e.g., processability, mechanical, thermal).…”

Combustion of fossil fuels and many other industrial activities inevitably produces carbon dioxide (CO2) that is released into the atmosphere and is currently deemed to be among the major contributors to global warming. One of the prominent solutions proposed to mitigate global warming concerns from CO 2 , capture and storage (CCS), did not attract many CO 2 emitting industries as expected, mainly because of economic reasons. On the contrary, environmental pollution concerns associated with plastic waste, and the demand for sustainable feedstock for their production constitute grand challenges facing our society with regard to the production and use of plastics. As a result, the materials science community is striving to generate sustainable and biodegradable plastics to substitute conventional synthetic plastics from resources that do not pose direct completion with food production. This manuscript aims to provide a general overview of the recent progress achieved in CO 2 based polymers for sustainable biopolymers such as co-polymers, and polymer blends. The synthesis, material properties, processability, and performances of important CO 2 based co-polymers are critically reviewed. Furthermore, a critical review of CO 2 co-polymers as components of polymer blend with a focus on the most relevant CO 2 based aliphatic polycarbonates, poly (propylene carbonates) (PPC), is conducted.

The evolving field of digital manufacturing includes additive manufacturing (AM) that builds computationally sliced parts layer-by-layer. AM popularity continues to grow partially due to its potential to accelerate the transition to a circular economy. This thesis aims to help mitigate waste products using four novel polymer composites designed and developed for use with either fused filament fabrication (FFF) or direct writing (DW). These polymer composites are: 1) Simulation verified and AM printed triply periodic minimal surface lattice structures embedded with heat storage materials. Diamond TPMS geometry bentonite/CaCl2 embedded prints of low packed configuration adsorb <19.1% total dry cylinder weight and reaches 38.3 °C bulk temperature when stacked in an open reactor. 2) Microporous zeolite composites for carbon capture strengthened using novel sacrificial polymer content. Zeolite 13X composite UCS increases from 4.92 (±1.22) to 7.75 (±0.75) MPa with the addition of 4 wt% CSR providing a composite BET surface area of 148 (±17)cm3/g. 3) Printer filaments made from rPP hospital blue wrap previously destined for landfill or incineration. MFI is reduced from 103 (±8) to 45 (±2)g/10mins when increasing SEBS content from 9.1 wt% to 20 wt%. The reduced MFI facilitates filament extrusion and subsequent printing of tensile and impact samples with tensile strength and impact energy absorption up to 22.5 (±1.2) MPa and 14 (±0.8) kJ/m2, respectively. 4) Epoxy matrix composites for;i) weight saving applications and ii) bone-like composite manufacture to improve surgical training and patient communication. Drilled compression strength of bone-like epoxy matrix composites encompassed those of drilled bone compression strength, ranging between a 5 wt% gypsum and 20 wt%hydroxyapatite composite of 2.7 (±0.3) MPa to a 1 wt% PE, 40 wt% GY and 5wt% HA composite of 6.5 (±0.5) MPa. This thesis contributes a furthered understanding of low-cost desktop AM as utilised for local acquisition of custom engineering products that necessitates minimal lead times and transportation.

Conventional lithium‐ion batteries (LIBs) are constantly evolving to improve their electrochemical performance and safety. In the past decade, research on electrode and electrolyte materials has significantly promoted the development of conventional LIBs. However, the current collector (CC) in conventional LIBs has not received sufficient attention. As a transfer unit that collects and disperses electrons from electrodes and transports them to the load, the performance of the CC significantly affects the performance of LIBs. This article reviews the impact of the CC on the electrochemical performance and safety of conventional LIBs in four aspects: CC requirements, manufacturing process, surface coating modification, and multifunctionalized CCs. Meanwhile, this review provides an objective summary and prospect on the transition from single‐functionality to multifunctionality requirements for CC, as well as the future needs for CC development and the technical hurdles that should be overcome. The article focuses on providing a detailed insight into the important impact of CCs on conventional LIBs, which has not received enough attention in the past. It emphasizes the need and urgency for the development of multifunctional CCs to provide new ideas for improving the performance of conventional LIBs.
