TL;DR: In this paper, the authors investigated the upward flame spread over a homogenous PMMA plate and an array of discrete thermally thin PMMA elements, and the experimental results showed that the flame spread rate peaks in the case of discrete PMMA element with a fuel coverage around 80% rather than 100% (the homogenous case).
Abstract: Experiments and theoretical analysis were conducted to investigate the upward flame spread over a homogenous PMMA plate and an array of discrete thermally thin PMMA elements. In the experiment, a digital video camera was used to record the flame spread process. An electronic balance and thermocouples were adopted to monitor the mass loss and pyrolysis front position, respectively, as a function of time. In the theoretical analysis, the mass loss rate of PMMA was correlated to the heat transfer during flame spread. The experimental results show that the flame spread rate peaks in the case of discrete PMMA elements with a fuel coverage around 80% rather than 100% (the homogenous case) because the gap with an appropriate spacing between neighboring elements accelerates the flame spread. However, the flame cannot spread over an array of discrete fuels at a coverage of 50% or smaller where the gap is too large to allow effective heat transfer required for flame spread. A smaller coverage of PMMA results in a larger mass loss rate per area since the gaps between elements can entrain more air to promote the burning. A logarithmic relation, that can well describe the mass loss rate as a function of PMMA coverage, was proposed based on the theoretical analysis and the fitting of experimental measurements.

TL;DR: In this paper, the mass loss rate of rigid polyurethane foam (RPU) was predicted by numerical models with a multi-step thermal degradation process based on thermogravimetric and combustion experiments.
Abstract: To predict the ignition time and mass loss rate of rigid polyurethane foam (RPU) under various radiative conditions, numerical models with a multi-step thermal degradation process have been developed based on thermogravimetric and combustion experiments. Kinetic parameters are computed via Particle Swarm Optimization with a five-step mechanism. Combustion properties of RPU under various external radiative conditions have been analyzed. From both surface absorption and in-depth absorption, one-dimensional ignition models have been established and solved via COMSOL Multiphysics. According to the ignition criterion, ignition temperature, the numerical ignition model has been established and validated by experimental results. The critical mass flux and its relationship with the external heat flux have been discussed. Moreover, the mass loss rate has been predicted by numerical models. The proposed models in this work potentially have the guiding significance for charring property polymer combustion.

TL;DR: A comprehensive review of biomedical polymers can be found in this paper , where the authors summarize the most recent advances in the synthesis and application and discuss the comprehensive understanding of their property-function relationship for corresponding biomedical applications.
Abstract: Biomedical polymers have been extensively developed for promising applications in a lot of biomedical fields, such as therapeutic medicine delivery, disease detection and diagnosis, biosensing, regenerative medicine, and disease treatment. In this review, we summarize the most recent advances in the synthesis and application of biomedical polymers, and discuss the comprehensive understanding of their property-function relationship for corresponding biomedical applications. In particular, a few burgeoning bioactive polymers, such as peptide/biomembrane/microorganism/cell-based biomedical polymers, are also introduced and highlighted as the emerging biomaterials for cancer precision therapy. Furthermore, the foreseeable challenges and outlook of the development of more efficient, healthier and safer biomedical polymers are discussed. We wish this systemic and comprehensive review on highlighting frontier progress of biomedical polymers could inspire and promote new breakthrough in fundamental research and clinical translation.
