Abstract


In this project we are using recycled HDPE along with woodflour as particulate filler and nanoclay/microclay to study the performance of these wood plastics composites. RecycledHDPE was melted-blended with wood flour (10%,20%&30%) using the twin screwcompounding extruder. Also nano clay (1% and 3%) was added with recycled HDPE containing 30% wood flour and also microclay (1%, 3%, 5% and7%) was added with nanoclay 3% containing recycled HDPE with 30%wood flour. PE-g-MAH was added as compatibilizer. The test specimens were prepared by injection molding machine as per ASTM standards. The mechanical, electrical, and physical properties were evaluated. The test results of wood plastics composites made with recycled HDPE indicated that the mechanical properties like tensile strength, tensile modulus, flexural strength, flexural modulus, and hardness are improved.The elongation at break and izod impact strength were lowered. Wood flour (30%) reinforced recycled HDPE has higher mechanical properties with optimum impact strength than other formulations with and without nanoclay/microclay. Electrical properties like volume resistivity, surface resistivity, arc resistance and dielectric strength were decreased as the wood flour content was increased. The melt flow index was decreased, density increased. The mechanical properties ofwood recycled plastics composites were not affected or improved when nanoclay was used, when microclay was added then the tensile strength was little lowered and other mechanical properties were better than recycled HDPE but lower than wood plastic composites with and without nanoclay

Call for Submissions

We welcome submissions for the coming issue that will be officially published in March 2022. We are committed to providing results of reviewing within two weeks, and publishing the paper within one month from the submission date (subjected to responses by authors). This means accepted papers will be available online even before the issue is published officially.

Publons Partners

Journal of Polymer Science and Technology (JPST) is now one of Publons Partners. This means biodata of reviewers in Publons will be automatically updated once reviewing on articles submitted to JPST is completed (subjected to terms and conditions).

How to promote journal articles

Promoting your journal article is imperative to maximise the exposure, enhance the discoverability and increase engagement with readers and other academics. Together with the publisher, as an author, you can help to promote your newly published articles via the following:

1) Institutional webpage.
Provide the link of your latest article in your institutional website. The webpage visitors who view your profile will be able to see your latest research and publications.

2) Social media.
The rise of the social media has also profoundly affected the publishing fraternity. More and more users have chosen the social media platforms as a way of sharing. Social media sharing helps foster convenient dissemination of information, which can be achieved within a short time. You can share your article in major online social media platforms including Twitter, Facebook, LinkedIn and so on.

3) Utilise scholarly networking and reference platforms.
A scholarly or academic networking platforms such as Academia.edu, MyNetResearch, ResearchGate, Mendeley and so on are indeed useful as they help bring scholars of common areas of expertise close together.

4) Press Releases.
If your article involves a new, significant or important discovery, consider linking up with media organisations for a press release. This brings your work to the mainstream media.

5) Blog.
If you keep a personal blog, you can get your blog readers updated with the list of your most recently published articles and the development in your area of research. Linking your article in your personal blog can vastly enhance the discoverability. Discuss briefly about the article and how the users might benefit from it.

6) Add to reading list or assignment.
Add your article (or the journal your article is published) as essential reading to your students. You may also create related assignments, e.g. review of the article, or have them discussed about the write up in class.

7) Add to your signature.
Announce your latest publication underneath your signature. Provide a link where the article can be downloaded/viewed.
