Bioplastics

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Polymers

Polymers

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...

Polymer Classification: Architecture

Polymer Classification: Architecture

Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...

Polymer Classification: Stereospecificity

Polymer Classification: Stereospecificity

Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...

Background:

Geopolymers are inorganic aluminosilicate polymers, traditionally viewed as sustainable alternatives to ordinary cement.
Recent literature often oversimplifies their environmental benefits, neglecting activator production and curing impacts.

Purpose of the Study:

To re-evaluate geopolymers as a versatile chemical platform beyond their role as sustainable binders.
To critically analyze the sustainability of geopolymers using life-cycle assessments.
To examine the evolution of geopolymer systems from bulk materials to nanoengineered and hybrid structures.

Main Methods:

Critical analysis of existing literature, including life-cycle assessments.
Examination of geopolymerization pathways, nanoscale structural disorder, and activator chemistry.
Review of research on halloysite-based systems and interfacial engineering strategies.

Main Results:

Geopolymer properties are controllable through dissolution-condensation, structural disorder, and activator chemistry.
Halloysite-based geopolymers have evolved into self-assembled inorganic films with tunable mesoscopic morphology.
Geopolymerization enables structural conversion across nano-, meso-, and macroscales.

Conclusions:

Geopolymers offer potential for advanced applications in barriers, adsorption, CO2 capture, and environmental remediation.
Future research should focus on sustainable activation strategies and chemically adaptable systems.
Design principles emphasizing activation chemistry, structural control, and morphological programmability are key for developing functional geopolymer materials.
