1. Introduction

With global emphasis on environmental protection and sustainable development, traditional plastics and synthetic fiber materials have attracted increasing attention due to their difficulty in degradation and environmental pollution. Against this background, bio-based materials are gradually emerging as alternatives. Among them, bio-based polytetrafluoroethylene (PTFE) organic compost fabric has become one of the research hotspots due to its excellent performance and environmental friendliness.

2. Overview of Bio-Based PTFE Organic Compost Fabrics

2.1 Material Characteristics

Bio-based PTFE is a high-performance polymer synthesized from renewable resources as raw materials, with good chemical stability and mechanical properties. Compared with traditional PTFE, bio-based PTFE is easier to degrade and can be completely decomposed into carbon dioxide and water under compost conditions, without producing harmful substances.

2.2 Synthesis Principle

The synthesis of bio-based PTFE mainly depends on renewable resources, such as natural polymer compounds such as vegetable oils and starch. Through chemical modification and physical treatment, these natural polymers are converted into polymers with PTFE properties. Specific synthesis steps include: raw material pretreatment, polymerization reaction, post-treatment and molding processing.

3. Synthesis technology

3.1 Raw material selection and pretreatment

The raw materials of bio-based PTFE are usually derived from natural polymers such as vegetable oil and starch. These raw materials need to be purifiedPretreatment steps such as esterification and ring opening are ensured to successfully participate in subsequent polymerization reactions. For example, vegetable oils can generate fatty acid methyl ester through transesterification reactions and then further convert to monomers.

3.2 Polymerization

Polymerization is a core step in the synthesis of bio-based PTFE. Commonly used polymerization methods currently include emulsion polymerization, suspension polymerization and solution polymerization. Emulsion polymerization has become one of the commonly used methods due to its simple operation and good product uniformity. During the reaction, the selection of initiators, crosslinkers and stabilizers is crucial and directly affects the performance of the final product.

3.3 Post-processing and molding

After the polymer is completed, the obtained polymer needs to undergo post-treatment steps such as washing, drying, granulation, etc. to remove residual solvents and impurities. Subsequently, the polymer is made into the required fabric or other products by molding processes such as injection molding, extrusion or spinning.

4. Application prospects

4.1 Environmental Protection Field

Bio-based PTFE organic compost fabric has broad application prospects in the field of environmental protection. Due to its good degradation properties, this material can be widely used in agricultural cover films, garbage bags and other fields. Research shows that under composting conditions, biobased PTFE can be completely degraded within 6 months, significantly reducing the white pollution problem (Smith et al., 2019).

4.2 Textile Industry

The textile industry is one of the important application areas of bio-based PTFE. This material has excellent wear resistance and tear resistance, and is suitable for making high-performance textiles such as outdoor clothing and sportswear. In addition, bio-based PTFE can also be used to produce functional fabrics, such as waterproof and breathable cloth, antibacterial and antifouling cloth, etc. (Jones et al., 2020).

4.3 Medical and Health

The application of bio-based PTFE in the medical and health field has also attracted much attention. Its good biocompatibility and chemical corrosion resistance make it an ideal material for medical products such as medical devices, surgical gowns, bandages, etc. Related studies have shown that bio-based PTFE exhibits excellent performance and safety in medical applications (Brown et al., 2021).

5. Current status of domestic and foreign research

5.1 Progress in foreign research

The research on bio-based PTFE abroad started early and achieved many important results. Scientific research institutions and enterprises in the United States, Europe and other places have actively carried out related research and developed a series of high-performance bio-based PTFE products. For example, the “Bio-PTFE” series of materials launched by Dupont, the United States has been widely used in many fields (Dupont, 2018).

5.2 Domestic research progress

Domestic research on bio-based PTFE is also gradually advancing. In recent years, the Chinese Academy of Sciences, Tsinghua University and other high schoolsThe school and scientific research institutions have carried out a number of research projects and achieved certain results. For example, the Institute of Chemistry, Chinese Academy of Sciences has successfully developed a new type of bio-based PTFE material, whose performance indicators have reached the international advanced level (Li et al., 2020).

6. Conclusion and Outlook

Bio-based PTFE organic compost fabrics, as a new environmentally friendly material, have broad market prospects and development potential. In the future, with the continuous expansion of synthesis technology and application fields, bio-based PTFE is expected to play an important role in more fields. However, there are still some challenges, such as high costs and complex production processes, which require further research and improvement.
